Hesiod, the Homeric Hymns and Homerica/Hymn XX (To Hephaestus)
Sing, clear-voiced Muse, of Hephaestus famed for inventions. With bright-eyed Athene he taught men glorious crafts throughout the world,—men who before used to dwell in caves in the mountains like wild beasts. But now that they have learned crafts through Hephaestus the famed worker, easily they live a peaceful life in their own houses the whole year round.
Be gracious, Hephaestus, and grant me success and prosperity!
