The Roman historian Titus Livius (Livy, 59 B.C.--A.D. 17) is well known for the 142 books of his Ab urbe condita (“From the Founding of the City”). Only Books 1--10 and 21--45 have survived. The famous defeat by Hannibal of the Roman forces under Flaminius at the battle of Trasimeno Lake is described in Book 22.
