Staphylus was the name of two characters of note. The first was the son of Dionysus and Ariadne, who went with the Argonauts. The second was a goatherd in the service of Oeneus who was alleged to have discovered the grape.
For both men there are obvious 'winy' associations, so it is hardly surprising to find that the name means 'bunch of grapes' (staphyle). The brother of the first Staphylus mentioned here was Oenopion (which see for yet another vinous name).
