|Pan Playing Double Aulos Among the White Violets|
Now just to confuse things, there was a transverse flute in use in ancient Greece. It was considered a country instrument, not very sophisticated and linked to shepherds. There are almost no mythological stories that feature this instrument and the only reference to a God playing one (that shouldn't actually read aulos that is) that I have run across is Pan and I'm not sure about that one. It is possible that the original Greek text said panpipes or syrinx instead of flute, another common mistranslation. Although since Pan was a God of shepherds, it is not impossible that in this case, they actually meant the transverse flute.
