Note 213 — Chapter VII · ACTIUM
Reading edition
The earlier writers, Horace (Od. i. 37, 27) and Velleius (2, 87), seem to have no doubt about the snake story. Livy (as we have him) says nothing either way except that she died by suicide (Ep. 133). It is the later writers who express the doubt, Suet., Aug. 17; Plut., Ant. 86; Dio, 51, 14.
