Key takeaways

  • James Ussher belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect James Ussher to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of James Ussher from memory before moving on to harder problems.

Reference excerpt

James Ussher (or Usher; 4 January 1581 – 21 March 1656) was the Church of Ireland Archbishop of Armagh and Primate of All Ireland between 1625 and 1656. He was a prolific Irish scholar and church leader, who today is most famous for his identification of the genuine letters of the church father, Ignatius of Antioch, and for his chronology that sought to establish the time and date of the creation as "the entrance of the night preceding the 23rd day of October ... the year before Christ 4004"; that is, around 6 pm on 22 October 4004 BC, per the proleptic Julian calendar.

Education

Ussher was born in Dublin to a well-to-do family. His maternal grandfather, James Stanihurst, had been speaker of the Irish parliament. Ussher's father, Arland Ussher, was a clerk in chancery who married Stanihurst's daughter, Margaret (by his first wife Anne Fitzsimon), who was reportedly a Roman Catholic. Ussher's younger and only surviving brother, Ambrose, became a distinguished scholar of Arabic and Hebrew. According to his chaplain and biographer, Nicholas Bernard, the elder brother was taught to read by two blind, spinster aunts. A gifted polyglot, he entered Dublin Free School and then the newly founded (1592) Trinity College Dublin on 9 January 1594, at the age of thirteen (not an unusual age at the time). He had received his Bachelor of Arts degree by 1598 and was a fellow and MA by 1600 (though Bernard claims he did not gain his MA till 1601). In May 1602, he was ordained in the Trinity College Chapel as a deacon in the Protestant, established, Church of Ireland (and possibly priest on the same day, while Martin Gorst says that he became a priest on 20 December 1601) by his uncle. Ussher went on to become Chancellor of St Patrick's Cathedral, Dublin in 1605 and Prebend of Finglas. He became Professor of Theological Controversies at Trinity College and a Bachelor of Divinity in 1607, Doctor of Divinity in 1612, and then Vice-Chancellor in 1615 and vice-provost in 1616. In 1613, he married Phoebe, daughter of a previous Vice-Provost, Luke Challoner, and published his first work. In 1615, he was closely involved with the drawing up of the first confession of faith of the Church of Ireland, the Irish Articles of Religion.

Early life and career James was born in the parish of St. Nicholas, to Arland Ussher (1545–1598) and Margaret Ussher (née Stanihurst) (1547–1601). It is recorded in Alfred Webb's, A Compendium of Irish Biography (1878) that his father, a clerk in the court of Chancery, was said to have been descended from one, Neville, who came over (to Ireland) with King John in the capacity of usher and had changed his name to that of his office. James was taught to read by two aunts who had been blind from infancy, to whom he ever afterwards looked back with affection and respect. From eight to thirteen years of age, he attended the school kept by Fullerton and Hamilton, private emissaries of James VI of Scotland, sent to keep up his influence in Ireland, in view of the prospect of his succeeding to the throne of England and Ireland." James's abilities, diligence, and loving disposition from youth are described as "attracting the esteem of all with whom he came in contact." He became one of the first and leading scholars of Trinity College, Dublin (opened 1593). In the beginning of 1614, he married his cousin, Phoebe, daughter of his maternal uncle Dr Lucas Challanor. Webb tells how Phoebe had been enjoined by her father's will, bequeathing her a considerable property, not to marry any other than Dr. Usher, "should he propose himself." 1619 Ussher travelled to England, where he remained for two years. His and Phoebe's only child was Elizabeth Ussher (1619–93), who married Sir Timothy Tyrrell, of Oakley, Buckinghamshire. She was the mother of James Tyrrell. Dr. Ussher became prominent after meeting James I. In 1621, James I nominated Ussher Bishop of Meath. He became a national figure in Ireland, becoming Privy Councillor in 1623 and an increasingly substantial scholar. A noted collector of Irish manuscripts, he made them available for research to fellow scholars such as his friend, Sir James Ware. From 1623 until 1626, he was again in England and was excused from his episcopal duties to study church history. He was nominated Primate of All Ireland and Archbishop of Armagh in 1625 and succeeded Christopher Hampton, who had succeeded Ussher's uncle Henry twelve years earlier.

Primate of All Ireland

After his consecration in 1626, Ussher found himself in turbulent political times. Tension was rising between England and Spain. To secure Ireland Charles I offered Irish Catholics a series of concessions, including religious toleration, known as The Graces, in exchange for money for the upkeep of the army. Ussher was a convinced Calvinist. He was dismayed that Papists might obtain power. He called a secret meeting of the Irish bishops in his house in November 1626, the result being the "Judgement of the Arch-Bishops and Bishops of Ireland". This begins:

Worked examples

Example 1 — a first encounter with James Ussher

Start with the simplest possible case. Write down what James Ussher claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to James Ussher before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about James Ussher ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of James Ussher

In research
James Ussher appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses James Ussher in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
James Ussher is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1581 births, 1656 deaths, 16th-century Anglican theologians, so understanding it makes those chapters shorter.
In everyday life
Look for James Ussher outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
