For since the god is said to have been summoned for this purpose, that he might drive away utterly all the causes by which pestilence was excited, it followed that the state should be safe, and should be always maintained free from pestilential blasts, and unharmed. But yet we see, as was said before, that it has over and over again had seasons made mournful by these diseases, and that the manly vigour of its people has been shattered and weakened by no slight losses. Where, then, was &#198;sculapius? where that deliverer promised by venerable oracles? Why, after temples were built, and shrines reared to him, did he allow a state deserving his favour to be any longer plague-stricken, when he had been summoned for this purpose, that he should cure the diseases which were raging, and not allow anything of the sort which might be dreaded to steal on them afterwards?
