Tacitus, The Annals — Book 14 (1876)
“ Songs indeed, he said, were sacred to Apollo, and it was in the dress of a singer that that great and prophetic deity was seen in Roman temples as well as in Greek cities. He could no longer be restrained, when Seneca and Burrus thought it best to concede one point that he might not persist in both. A space was enclosed in the Vatican valley where he might manage his horses, without the spectacle being public. Soon he actually invited all the people of Rome, who extolled him in their praises, like a mob which craves for amusements and rejoices when a prince draws them the same way. ”
