ἘγχώΣεμλη ӣὕτως καλεῖτо, says the lexicographer, from a source which is unknown, but would appear to be late, since it uses a past tense. Where or by whom Semele was so named is not stated, nor has any explanation been given, so far as I know, that is at all satisfactory, for she certainly has nothing to do with swords. I suggest that she was never called anything of the kind, and the statement arises from a comedian's jest. Aristophanes (Ran. 22) speaks of Διννσоς Σιαμνоν, and the scholiast is careful to inform the humourless who read this play that it is a joke, παρ' ὑπνоιαν, instead of νἱς Δις. So no lexicographer ever tells us that Stamnios is a title of Zeus. I suggest that somewhere, by Aristophanes or another, Dionysos was called νἱς Ἐγχоς, ‘son of Pour-Out,’ a comic formation from γχεῖν. If such a passage came into the late classical or the mediaeval world unguarded by a scholiast, it would be taken with the same seriousness which has attended sundry witticisms directed at Kleon and other butts of Comedy. The reasoning would be most syllogistic and accurate, as thus:

Encho is the mother of Dionysos.

But Semele is the mother of Dionysos.

Therefore Encho is Semele, Q.E.D.
