Age 20. Studying in Rome under Q. Mucius Scaevola the Augur, the great jurist of the age, and reading philosophy under the Epicurean Phaedrus and the Stoic Diodotus. Marius dies in January at his seventh consulship; the civil war between the Marians and the absent Sulla grinds on in Italy. Cicero's youthful verse translation of Aratus belongs somewhere in this period.

Age 61. Tullia, his daughter, dies in February after childbirth.
