Cicero (106-43 BC) finished writing his 'De officiis' ('On [moral] duties') in November 44 BC. It consists of three books of moral advice, written in the form of a letter to his son, Marcus, who was studying philosophy at the time. It deals with the four cardinal virtues (wisdom, justice, fortitude, and temperance), and goes on to show how success and happiness in life is dependant on striving towards these virtues. This copy of the text was owned by St. Augustine's Abbey, Canterbury. This flyleaf is inscribed with (from top to bottom): a typical St. Augustine's press-mark; the author and title; an ownership note of St. Augustine's; and a note recording that it was bought for 8 pence by Thomas Linacre (1460-1524), who was from Canterbury, and went on to become Henry VIII's doctor and a noted Greek scholar.
