The Essays was the first published book by the philosopher, statesman and jurist Francis Bacon. The Essays are written in a wide range of styles, from the plain and unadorned to the epigrammatic. They cover topics drawn from both public and private life, and in each case the essays cover their topics systematically from a number of different angles, weighing one argument against another. Though Bacon considered the Essays 'but as recreation of my other studies', he was given high praise by his contemporaries, even to the point of crediting him with having invented the essay form. The 19th century literary historian Henry Hallam wrote that 'They are deeper and more discriminating than any earlier, or almost any later, work in the English language'. Bacon’s genius as a phrase-maker appears to great advantage in the later essays. In 'Of Boldness' he wrote, 'If the Hill will not come to Mahomet, Mahomet will go to the hill', which is the earliest known appearance of that proverb in print. The phrase 'hostages to fortune' appears in the essay 'Of Marriage and Single Life'. The 1999 edition of The Oxford Dictionary of Quotations includes no less than 91 quotations from the Essays.
