Alter erit tum Tiphys, et altera quae vehat Argo Delectos heroas: erunt etiam altera bella, Atque iterum ad Trojam magnus mittetur Achilles. -- Virgil, Eclogue, iv, 34-36.The fancy, we cannot call it the doctrine, appears in the mythus of Plato, Politicus, 270 sq.
The distant way in which St Thomas speaks of Plato is in strong contrast with his familiar mention of 'the Philosopher.' See B. II, Chap. LVII, note [2.57a].
