The d’Arcy family, who are Catholics, suffer under the Penal Laws. In 1739 d’Arcy is sent to Paris for his education. He is tutored in mathematics by Jean-Baptiste Clairaut, and becomes a friend of Jean-Baptiste’s son, Alexis-Claude Clairaut, who is a brilliant young mathematician. d’Arcy makes original contributions to dynamics. He is best known for his part in the discovery of the principle of angular momentum, in a form which is known as “the principle of areas,” which he announces in 1746.
Perhaps seeking more adventure than an academic life can provide, d’Arcy enlists in the French army. He fights in Germany in the regiment of Condé and serves as an aide-de-camp to Marshal Saxe at the Battle of Fontenoy. He obtains the title of “Count” in the French nobility and is a generous patron of Irish refugees in France. He sails for Scotland in 1745, attempting to fight in “Bonnie” Prince Charlie‘s rising, but his ship is captured, and he is taken prisoner.
After his release, d’Arcy returns to France where he continues both his scientific and military careers. In addition to his contributions to dynamics, he performs research on artillery and electricity. One of his experiments on visual perception, reported in 1765, is often referenced. It involves a rotating disk on which a burning coal ember is placed. When the disk is spun at an angular velocity exceeding seven revolutions per second, a full circle of light is perceived. This and other experiments make d’Arcy the first person to demonstrate the illusion of a moving image, although Joseph Plateau greatly elaborates on this initial finding.
Richard John Griffith, Irish geologist, mining engineer, and chairman of the Board of Works of Ireland, is born in Hume Street, Dublin, on September 20, 1784. He completed the first complete geological map of Ireland and is author of the valuation of Ireland, known ever since as Griffith’s Valuation.
In 1799 he obtains a commission in the Royal Irish Artillery, but a year later, when the corps is incorporated with that of England, he retires, and devotes his attention to civil engineering and mining. He studies chemistry, mineralogy, and mining for two years in London under William Nicholson and afterwards examines the mining districts in various parts of England, Wales, and Scotland.
While in Cornwall he discovers ores of nickel and cobalt in material that has been rejected as worthless. He completes his studies under Robert Jameson and others at Edinburgh, is elected a Fellow of the Royal Society of Edinburgh in 1807, a member of the newly established Geological Society of London in 1808, and in the same year he returns to Ireland.
In 1809, he is appointed by the commissioners to inquire into the nature and extent of the bogs in Ireland and the means of improving them. In 1812 he is elected Professor of Geology and Mining Engineer to the Royal Dublin Society. Shortly afterwards he expresses his intention of preparing a geological map of Ireland. During subsequent years he makes many surveys and issues many reports on mineral districts in Ireland. These form the foundation of his first geological map of the country in 1815. He also succeeds Dr. Richard Kirwan as government inspector of mines in Ireland. In 1822 Griffith becomes engineer of public works in Cork, Kerry, and Limerick, and is occupied until 1830 in repairing old roads and in laying out many miles of new roads in some of the most inaccessible parts of the country.
Meanwhile, in 1825, he is appointed by the government to carry out a boundary survey of Ireland. He is to mark the boundaries of every county, barony, civil parish, and townland in preparation for the first Ordnance Survey. He is also called upon to assist in the preparation of a parliamentary Bill to provide for the general valuation of Ireland, which passes in 1826. Griffith is appointed Commissioner of Valuation in 1827 but does not start work until 1830 when the new 6″ maps become available from the Ordnance survey and which he is required to use as provided for by statute. He continues to work on this until 1868. On Griffith’s valuation the various local and public assessments are made.
His extensive investigations furnish him with ample material for improving his geological map and the second edition is published in 1835. A third edition on a larger scale (1 in. to 4 m.) is issued under the Board of Ordnance in 1839 and it is further revised in 1855. For this great work and his other services to science Griffith is awarded the Wollaston Medal by the Geological Society in 1854. In 1850 he is made chairman of the Irish Board of Works and in 1858 he is created a baronet.
Griffith dies at the age of 95 at his residence in Dublin on September 22, 1878. At the time of his death, he is the oldest surviving fellow of the Geological Society of London and is the last survivor of the long-since disbanded Royal Irish Regiment of Artillery. He is buried alongside his wife, Maria Jane, in Mount Jerome Cemetery, Harold’s Cross, Dublin.
The Second Battle of Athenry takes place on August 10, 1316. The English Colonists defeat the Irish in a very bloody battle. This is one of the most decisive battles of the Bruce campaign in Ireland (1315-1318).
The numbers involved are unknown and can only be estimated. The royal army is believed to have been as much as a few thousand, while that of Athenry is probably several hundred less. While it is doubtful that there are any more than seven thousand, the list of participants on the Irish side alone indicates that an overall figure of at least three to four thousand are involved. The English claim that they take some 1,100 heads from the Irish on that day.
Unlike the First Battle of Athenry in 1249, no account is given of the battle itself in any surviving account. Even the site of the battle itself is uncertain.
Although details of the battle are very sketchy at best, the Irish certainly meet with catastrophe. Fedlim Ó Conchobair and Tadhg Ó Cellaigh, King of Uí Maine, are among those who are killed along with numerous other kings and chieftains of the Gaels.
At the 2007 Open Championship, Harrington defeats Sergio García in a four-hole playoff at Carnoustie, becoming the first Irishman to win The Open Championship in 60 years, and the first ever from the Republic of Ireland. Both players go into the playoff having shot a 7-under 277 for the championship. Harrington subsequently wins by one stroke in the playoff.
Harrington is the first European golfer to secure a major victory since Paul Lawrie on the same course in 1999 and Ireland’s first since Fred Daly in 1947. President Mary McAleese is the first to convey her congratulations to Harrington, while Labour sports spokesman Jack Wall says, “Pádraig Harrington’s magnificent victory in the Open without doubt represents one of the greatest days in the history of Irish sport.”
A year later at the 2008 Open Championship, it is unclear if Harrington would get a chance to defend his Open title at Royal Birkdale Golf Club as eight days prior to the event he injures his wrist. However, he successfully defends his title, overcoming a 2-shot deficit to Greg Norman with a final round 69. He shoots a four-under-par 32 on the back nine, which enables him to pull away from Norman and Ian Poulter. His eagle on the par-5 17th all but seals the tournament. He is the first European golfer since James Braid in 1906 to retain the Claret Jug. The win moves him from fourteenth to third in the world rankings, behind only Tiger Woods and Phil Mickelson.
Just three weeks after winning the 2008 Open Championship, Harrington wins the PGA Championship over the South Course of the Oakland Hills Country Club, for his third major. Although at five over par after two rounds, he shoots eight under par for the weekend, carding successive scores of 66 in both the third and fourth rounds. His three under par 277 is two shots ahead of Sergio García and Ben Curtis. Harrington becomes the first European to win the PGA Championship since Tommy Armour in 1930 and is the first winner from Ireland.
Harrington’s victory in the PGA Championship secures his position as the number one player in Europe, earning him a spot in the 2008 European Ryder Cup team under captain Nick Faldo.
The assembly, inspired by the Jewish Sanhedrin, meets for the first time on July 4 in the council chamber at Whitehall. Cromwell opens proceedings with a speech around two hours long. He begins by summing up the “series of Providences” that have brought them to this point, starting with the Short Parliament and singling out 1648 as the “most memorable year that ever this nation saw.”
The assembly then adjourns before sitting in full on the following day. On that day they elect Francis Rous, initially as chairman. He is not known as Speaker until a month later. Henry Scobell is appointed as Clerk. On July 12, the assembly publishes a declaration declaring itself to be the parliament of the Commonwealth of England. This is the first time that it has been formally described as a parliament.
By early September, Cromwell is said to be growing frustrated with the assembly’s in-fighting between different groups. Attendance also begins to fall. Over one hundred members are present at most votes in July, dropping to an average turnout of 70 by October. Various bills inflame conflict between the radical and moderate members – bills to abolish the Court of Chancery, regulate legal fees, tithes, and speeding up the settlement of cases in the Court of Admiralty all become bogged down in conflict. At this point, however, radical members are still mainly outnumbered in votes by moderate and conservative members.
This changes during November and December when debate returns to the question of tithes. On December 6, the committee appointed to consider the question presents their report, covering the question of how unfit ministers are to be ejected, naming commissioners who will have the job of enacting this, and retaining support for tithes in prescribed circumstances. In a defeat for the moderates, the first clause is voted down 56 to 54. Two days later, moderates come to the House and demand that the assembly abdicate its powers, criticising radical members for threatening the well being of the Commonwealth by fomenting disagreement. Rous and around 40 members walk out and go to Cromwell at Whitehall, presenting a document signed by nearly 80 members that declares: “Upon a Motion this day made in the House, that the sitting of this Parliament any longer as now constituted, will not be for the good of the Commonwealth.” Those left in the house are soon confronted by troops requesting that they leave. On December 12, 1653, the members of the assembly vote to dissolve it.
It takes its name in memory of King William of Orange of the house of Orange who fights at the Battle of the Boyne, brings about the Glorious Revolution and the Bill of Rights giving the Westminster parliament ultimate power of the country rather than the Monarch. The Independent Order is small compared to the main organisation with 1,500 to 2,000 members. It is largely based around north County Antrim in Northern Ireland but has lodges around the world, including England, Scotland, and Australia. Its annual main Twelfth of July demonstration is held in a north Antrim town or village.
The first notable effect after the formation of the Independent Order is a more liberal interpretation of the rules of the “Old Order.” In the early years of the Institution, many suffer the full wrath of the “powers that be,” who are opposed to any splitting of the Orange Order. Jobs are lost, homes are burned, and their headquarters in Belfast is bombed.
Independent Orangeism today maintains that it is essential for the Orange Institution to be kept free from politics and to guard the principles of Reformation Protestantism. They often express alarm when they believe these principles are endangered by conciliatory politicians. They are opposed to ecumenism and, while being opposed to Orangeism being linked to the Ulster Unionist Party, they are not apolitical and tend to work alongside unionist politicians and parties.
The Institution also promotes Ulster Protestant history and proclaims the principle of “Liberty of Conscience.” They declare their right to think and act independently without direction from political or clerical masters, they seek to strengthen the position of Orangeism, and they often warn of the danger of the development of a social and cultural Orangeism devoid of Protestant principle.
Circa 1189 de Lacy is appointed Viceroy of Ireland, a position previously held by his father, Hugh de Lacy, Lord of Meath. He is replaced in 1190 by Guillaume le Petil. He is later reappointed to serve as viceroy from 1205 to 1210.
In 1199, King John authorises de Lacy to wage war on John de Courcy, who has conquered much of Ulster without help or permission from the King. Hugh captures de Courcy in 1204. An account of the capture appears in the Book of Howth.
After King John creates him Earl of Ulster in 1205, he makes what was de Courcy’s territory in Ulster the Earldom of Ulster. He grants Drogheda its charter and continues the conquest of the northeastern over-kingdom of Ulaid, building on de Courcy’s success, with the earldom spanning across the modern counties of Antrim and Down and parts of Londonderry.
In 1207, war breaks out between the Earl of Ulster and the justiciar. This brings King John to Ireland, where he expels the earl’s brother, Walter de Lacy, from Meath, and compels the earl himself to flee to Scotland.
For several years Ulster takes part in the wars in France, and de Lacy does not return to Ireland until 1221, when he allies himself with the O’Neills against the English. In 1226, his lands in Ulster are handed over to his brother Walter, but they are restored to him in the following year, after which date, he appears to loyally serve the king, being more than once summoned to England to give advice about Irish affairs.
De Lacy purportedly separates from his first wife and lives in adultery. He has legitimate and natural children. In 1226, his daughter by his first wife marries Alan, Lord of Galloway. He marries his second wife, Emmeline de Riddlesford, the daughter of Walter de Riddlesford around 1242. Hugh de Lacy dies shortly thereafter in 1242 or 1243. Emmeline’s second marriage takes place around 1243 with Stephen Longespee, grandson of Henry II of England, by whom she has two daughters, Ela Longespee, Lady of Ashby, and Emmeline Longespee, Lady of Offaly.
Left with no surviving legitimate children, the earldom of Ulster reverts to the crown upon de Lacy’s death.
Sir Arthur Ignatius Conan Doyle, British writer and physician, most noted for creating the fictional detective Sherlock Holmes and writing stories about him which are generally considered milestones in the field of crime fiction, is born at 11 Picardy Place, Edinburgh, Scotland, on May 22, 1859.
Doyle’s father, Charles Altamont Doyle, is an Englishman of Irish Catholic descent and his mother, Mary (née Foley), is Irish Catholic. Charles dies in 1893, in the Crichton Royal Hospital, Dumfries, after many years of psychiatric illness. Supported by wealthy uncles, Doyle is sent to the Jesuit preparatory school Hodder Place, Stonyhurst, at the age of nine. He then goes on to Stonyhurst College until 1875. From 1875 to 1876, he is educated at the Jesuit school Stella Matutina in Feldkirch, Austria. Doyle later rejects the Catholic faith and becomes an agnostic. He also later becomes a spiritualist mystic.
From 1876 to 1881 Doyle studies medicine at the University of Edinburgh Medical School. While studying, he begins writing short stories. His first published piece, The Mystery of Sasassa Valley, is printed in Chambers’s Edinburgh Journal on September 6, 1879. After stints as a ship’s doctor and a failed medical practice with former classmate George Turnavine Budd, Doyle arrives in Portsmouth in June 1882 and sets up a medical practice at 1 Bush Villas in Elm Grove, Southsea. The practice is slow to develop and while waiting for patients, Doyle again begins writing fiction. In 1890, Doyle studies ophthalmology in Vienna and moves to London.
A sequel to A Study in Scarlet is commissioned and The Sign of the Four appears in Lippincott’s Magazine in February 1890, the last under agreement with the Ward Lock company. Short stories featuring Sherlock Holmes are published in TheStrand Magazine.
In December 1893, wanting to dedicate more time to historical novels, Doyle has Holmes and Professor Moriarty plunge to their deaths together down the Reichenbach Falls in the The Final Problem. Public outcry, however, leads him to feature Holmes in 1901 in the novel The Hound of the Baskervilles. Holmes is ultimately featured in a total of 56 short stories, the last published in 1927, and four novels by Doyle.
Between 1888 and 1906, Doyle writes seven historical novels, which many critics regard as his best work. He also authors nine other novels and, later in his career between 1912 and 1929, five stories, two of novella length, featuring the irascible scientist Professor Challenger.
Doyle is a supporter of the campaign for the reform of the Congo Free State, led by the journalist E. D. Morel and diplomat Roger Casement. He becomes acquainted with Morel and Casement and, together with Bertram Fletcher Robinson, they inspire several characters in the 1912 novel The Lost World. When Casement is found guilty of treason against the Crown during the 1916 Easter Rising, Doyle tries unsuccessfully to save him from facing the death penalty, arguing that Casement has been driven mad and cannot be held responsible for his actions.
Found clutching his chest in the hall of Windlesham Manor, his house in Crowborough, East Sussex, on July 7, 1930, Doyle dies of a heart attack at the age of 71. At the time of his death there is some controversy concerning his burial place, as he is avowedly not a Christian, but rather considers himself a Spiritualist. He is first buried on July 11, 1930, in Windlesham rose garden. He is later reinterred together with his wife in Minstead churchyard in the New Forest, Hampshire.
In 484, Brendan is born in Tralee, County Kerry, in the province of Munster. He is born among the Altraige, a tribe originally centred around Tralee Bay, to parents called Finnlug and Cara. He is baptised at Tubrid, near Ardfert by Saint Erc, and is originally to be called “Mobhí” but signs and portents attending his birth and baptism lead to him being christened “Broen-finn” or “fair-drop.” For five years he is educated under Saint Ita, “the Brigid of Munster.” When he is six, he is sent to Saint Jarlath‘s monastery school at Tuam to further his education. Brendan is one of the “Twelve Apostles of Ireland,” one of those said to have been tutored by the great teacher, Finnian of Clonard.
At the age of twenty-six, Brendan is ordained a priest by Saint Erc. Afterwards, he founds a number of monasteries. Brendan’s first voyage takes him to the Aran Islands, where he founds a monastery. He also visits Hinba, an island off Scotland where he is said to meet Columcille. On the same voyage he travels to Wales, and finally to Brittany, on the northern coast of France. Between the years 512 and 530 Brendan builds monastic cells at Ardfert and, at the foot of Mount Brandon, Shanakeel— Seana Cill, usually translated as “the old church.” From here he supposedly sets out on his famous seven-year voyage for Paradise.
St. Brendan is chiefly renowned for his legendary journey to the Isle of the Blessed as described in the ninth century Voyage of St. Brendan the Navigator. Many versions exist that tell of how he sets out onto the Atlantic Ocean with sixteen pilgrims searching for the Garden of Eden. One of these companions is said to be Saint Malo, the namesake of Saint-Malo. This occurs sometime between 512 and 530 AD, before his travel to the island of Great Britain. On the trip, Brendan supposedly sees Saint Brendan’s Island, a blessed island covered with vegetation. He also encounters a sea monster, an adventure he shares with his contemporary, Saint Columba. The most commonly illustrated adventure is his landing on an island which turns out to be a giant sea monster called Jasconius or Jascon. This too, has its parallels in other stories, not only in Irish mythology but in other traditions, from Sinbad the Sailor to Pinocchio.
Brendan travels to Wales and the holy island of Iona, off the west coast of Scotland. Returning to Ireland, he founds a monastery at Annaghdown, where he spends the rest of his days. He also founds a convent at Annaghdown for his sister Briga. Having established the bishopric of Ardfert, St. Brendan proceeds to Thomond and founds a monastery at Inis-da-druim, in the present parish of Killadysert, County Clare, about the year 550. He then journeys to Wales and studies under Saint Gildas at Llancarfan, and then to Iona, for it is said that he leaves traces of his apostolic zeal at Kil-brandon and Kil-brennan Sound. After a three years’ mission in Britain, he returns to Ireland, and does more proselytising in various parts of Leinster, especially at Dysart, Killiney, and Brandon Hill. He establishes churches at Inchiquin, County Clare and at Inishglora, County Mayo, and founds Clonfert in County Galway around 557 AD.
Brendan dies on May 16, 577 at Annaghdown, while visiting his sister Briga. Fearing that after his death his devotees might take his remains as relics, Brendan arranges before his death to have his body secretly carried back to the monastery he founded at Clonfert concealed in a luggage cart. He is buried in Clonfert Cathedral.
Day-Lewis is the son of Frank Day-Lewis, Church of Ireland Rector of the parish, and Kathleen Blake. His father takes the surname “Day-Lewis” as a combination of the surnames of his own birth father (Day) and his adoptive father (Lewis). After the death of his mother in 1906, Day-Lewis is brought up in London by his father, with assistance of an aunt, spending summer holidays with relatives in County Wexford. He is educated at Sherborne School and at Wadham College, Oxford. In Oxford, Day-Lewis becomes part of the circle gathered around W. H. Auden and helps him to edit Oxford Poetry 1927. His first collection of poems, Beechen Vigil, appears in 1925.
In 1928, Day-Lewis marries Constance Mary King, the daughter of a Sherborne teacher, and works as a schoolmaster in three schools, including Larchfield School in Helensburgh, Scotland. During the 1940s he has a long and troubled love affair with the novelist Rosamond Lehmann. His first marriage is dissolved in 1951, and he marries actress Jill Balcon, daughter of Michael Balcon.
During World War II he works as a publications editor in the Ministry of Information, an institution satirised by George Orwell in his dystopian Nineteen Eighty-Four. During this time his work is now no longer as heavily influenced by Auden, and he develops a more traditional style of lyricism. Some critics believe that he reaches his full stature as a poet in Word Over All (1943), when he finally distances himself from Auden. After the war he joins the publisher Chatto & Windus as a director and senior editor.
