The Maenads (translates as "raving ones") female followers of Dionysus inspired into a state of ecstatic frenzy through a combination of dancing and intoxication.
They went into the mountains at night and practiced strange rites.

German philologist Walter Friedrich Otto writes:
The god-intoxicated celebrants draw milk and honey from the streams.
They strike rocks with the thyrsus, and water gushes forth.

They lower the thyrsus to the earth, and a spring of wine bubbles up.
If they want milk, they scratch up the ground with their fingers and draw up the milky fluid.
Honey trickles down from the thyrsus made of the wood of the ivy, they gird themselves with snakes and give suck to fawns and wolf cubs as if they were infants at the breast.

Fire does not burn them.
No weapon of iron can wound them, and the snakes harmlessly lick up the sweat from their heated cheeks.

Fierce bulls fall to the ground, victims to numberless, tearing female hands, and sturdy trees are torn up by the roots with their combined efforts.

Maenads' are found the later references as priestesses of the Dionystic cult.
In the third century BC, when an Asia Minor city wanted to create a maenadic cult of Dionysus, the Delphic Oracle bid them to send to Thebes for both instruction and three professional maenads, stating, "Go to the holy plain of Thebes so that you may get maenads who are from the family of Ino, daughter of Cadmus.
They will give to you both the rites and good practices, and they will establish dance groups (thiasoi) of Bacchus [ie: Dionysus] in your city."
