Ah! What another beautiful hymn! I'm specially biased, as its for Dionysos, but wow! Very well done!

I love your wording here:

Dionysos, deep well of ecstasy,
swiftly-moving impulse and languid grace,
your gift the sheer plunge of transformation,
we thank you for knowledge gained in madness,
for seeing through wild eyes, for ripped-raw nerves.

Once again! Great job!

Evoe!
