Aesculapius is struck by lightning, that he may rise into a god. Hercules, that he may put off the man, is burnt up in the fires of Oeta. Apollo fed the flocks of Admetus; Neptune founded walls for Laomedon, and received— unfortunate builder— no wages for his work. The cave of Jupiter is to be seen in Crete, and his sepulchre is shown; and it is manifest that Saturn was driven away by him, and that from him Latium received its name, as being his lurking-place.

Janus had received him to hospitality when he was driven away, from whose name the Janiculum is so called, and the month of January is appointed.
