Nature herself, indeed, seems to have given music to us as a benefit, to enable us to endure labors with greater facility, for musical sounds cheer even the rower; and it is not only in those works in which the efforts of many, while some pleasing voice leads them, conspire together that music is of avail, but the toil even of people at work by themselves finds itself soothed by song, however rude.

Even Odysseus didn’t dare to attempt that passage. But if you’ve got a crew that includes Heracles and Orpheus the sky’s the limit.
