Read "Picture by Piero di Cosimo" at The Eldritch Dark:
I assume that this haiku from Clark Ashton Smith (CAS) refers to "The Discovery of Honey by Bacchus" (shown above), a painting by Piero di Cosimo now held in the Worcester Art Museum in Massachusetts. Their website has some interesting background on the painting:
CAS' interpretation of the events depicted in the picture differs from that of the museum curators: in CAS' poem the "Satyrs loot the bee-tree", while the museum commentary notes that "satyrs and maenads...make noise to attract a swarm of bees to settle in a hollow tree." Those actions supposedly give rise to the mythical discovery of honey.
