Note 270:2 — Chapter XXVII
Reading edition
Dionysius of Halicarnassus, one of the most accurate historians of antiquity, says: "In the war with the Latins, Castor and Pollux appeared visibly on white horses, and fought on the side of the Romans, who by their assistance gained a complete victory. As a perpetual memorial of it, a temple was erected and a yearly festival instituted in honor of these deities." (Prog. Relig. Ideas, vol. i. p. 323, and Middleton's Letters from Rome, p. 103.)
