"...and [Sextus] was further elated when a cow spoke with a human voice, as they say, and bade him lay hold of the task before him, and when he had a dream in which a bull that had been buried in the city of Tucca seemed to urge him to dig up its head and carry it about on a pole, intimating that by this means he should conquer. Without hesitation, then, especially when he found the bull at the place where the dream said it was, he took the initiative by invading Africa."
- Cassius Dio XLVIII.21.2-3, translated by Earnest Cary
