Marcus Aurelius Antoninus was born in AD 121, in the reign of the emperor Hadrian. At first he was called Marcus Annius Verus, but his well-born father died young and he was adopted, first by his grandfather, who had him educated by a number of excellent tutors, and then, when he was sixteen, by Aurelius Antoninus, his uncle by marriage, who had been adopted as Hadrian's heir, and had no surviving sons of his own. Aurelius Antoninus changed Marcus' name to his own and betrothed him to his daughter, Faustina. She bore fourteen children, but none of the sons survived Marcus except the worthless Commodus, who eventually succeeded Marcus as emperor.

On the death of Antoninus in 161, Marcus made Lucius Verus, another adopted son of his uncle, his colleague in government. There were thus two emperors ruling jointly for the first time in Roman history. The Empire then entered a period troubled by natural disasters, famine, plague and floods, and by invasions of barbarians. In 168, one year before the death of Verus left him in sole command, Marcus went to join his legions on the Danube.

Apart from a brief visit to Asia to crush the revolt of Avidius Cassius, whose followers he treated with clemency, Marcus stayed in the Danube region and consoled his somewhat melancholy life there by writing a series of reflections which he called simply To Himself. These are now known as his Meditations, and they reveal a mind of great humanity and natural humility, formed in the Stoic tradition, which has long been admired in the Christian world. He died, of an infectious disease, perhaps, in camp on 17 March AD 180.

Edith Wharton (1862-1937) was a brilliant, clever American writer known for such works as The House of Mirth and Ethan Frome. She became the first woman to win a Pulitzer when she was awarded the 1921 Prize for her novel The Age of Innocence.

A member of the New York elite, Wharton funnelled her experiences into vivid portrayals and critiques of high society, while deftly exposing the painful tension between personal desires and societal norms. Wharton died in Paris in 1937 at the age of 75, having written 85 short stories, 16 novels, 11 works of nonfiction, and 3 books of poetry.

Virginia Woolf was born in London in 1882. After her father's death in 1904 Virginia and her sister, the painter Vanessa Bell, moved to Bloomsbury and became the centre of ‘The Bloomsbury Group’. This informal collective of artists and writers exerted a powerful influence over early twentieth-century British culture.

In 1912 Virginia married Leonard Woolf, a writer and social reformer. Three years later, her first novel The Voyage Out was published, followed by Night and Day (1919) and Jacob's Room (1922). Between 1925 and 1931 Virginia Woolf produced what are now regarded as her finest masterpieces, from Mrs Dalloway (1925) to The Waves (1931).

She also maintained an astonishing output of literary criticism, short fiction, journalism and biography. On 28 March 1941, a few months before the publication of her final novel, Between the Acts, Virginia Woolf committed suicide.

John Buchan was born in Perth. His father was a minister of the Free Church of Scotland; and in 1876 the family moved to Fife where in order to attend the local school the small boy had to walk six miles a day. Later they moved again to the Gorbals in Glasgow and John Buchan went to Hutchesons' Grammar School, Glasgow University (by which time he was already publishing articles in periodicals) and Brasenose College, Oxford.

His years at Oxford - 'spent peacefully in an enclave like a monastery' - nevertheless opened up yet more horizons and he published five books and many articles, won several awards including the Newdigate Prize for poetry and gained a First. His career was equally diverse and successful after university and, despite ill-health and continual pain from a duodenal ulcer, he played a prominent part in public life as a barrister and Member of Parliament, in addition to being a writer, soldier and publisher. In 1907 he married Susan Grosvenor, and the marriage was supremely happy. They had one daughter and three sons. He was created Baron Tweedsmuir of Elsfield in 1935 and became the fifteenth Governor-General of Canada, a position he held until his death in 1940. 'I don't think I remember anyone,' wrote G. M. Trevelyan to his widow, 'whose death evoked a more enviable outburst of sorrow, love and admiration.'

John Buchan's first success as an author came with Prester John in 1910, followed by a series of adventure thrillers, or 'shockers' as he called them, all characterized by their authentically rendered backgrounds, romantic characters, their atmosphere of expectancy and world-wide conspiracies, and the author's own enthusiasm. There are three main heroes: Richard Hannay, whose adventures are collected in The Complete Richard Hannay; Dickson McCunn, the Glaswegian provision merchant with the soul of a romantic, who features in Huntingtower, Castle Gay and The House of the Four Winds; and Sir Edward Leithen, the lawyer who tells the story of John MacNab and Sick Heart River, John Buchan's final novel. In addition, John Buchan established a reputation as an historical biographer with such works as Montrose, Oliver Cromwell and Augustus.
