Agricola (a-grick'o-la) (Cnaeus Julius), a Roman governor of Britain under Vespian, born A.D. 37. He subjected Scotland and Ireland, reduced the Britons and, by his able government, preserved these territories to the Romans. Domitian, jealous of his success, recalled him, and Agricola withdrew to his estate, where he died in 93. His life, written by his son-in-law, Tacitus, is extant, and is considered a model of biographical writing.
