Horatius, Sermones 1.5.100
Next day the weather was better, the road worse, even to the very walls of Barium that abounds in fish. In the next place Egnatia, which [seems to have] been built on troubled waters, gave us occasion for jests and laughter; for they wanted to persuade us, that at this sacred portal the incense melted without fire. The Jew Apella may believe this, not I. For I have learned [from Epicurus], that the gods dwell in a state of tranquillity; nor, if nature effect any wonder, that the anxious gods send it from the high canopy of the heavens.
