quote: Here was a cavern, awful and deep-withdrawn, impenetrable to the sunbeams...
summary: After a feast, King Evander explains that the local rites and altar honor
Hercules because he delivered the people from Cacus, a fire-breathing half-human
monster who lived in a cavern, stole cattle by craft, hid them, was exposed by
a lowing heifer, and was killed by Hercules. Evander then calls the men to perform
libations and supplication.
