The horned bacchante

The Bacchante 1853

Jean Leon Gerome 

In Roman mythology the bacchantes are the female 

followers of Bacchus, the god of wine and revelry;

 based on Greek myth of Dionysus and the maenads, see below.

From Wikipedia:

"[Maenad] literally translates as "raving ones". Often the maenads were portrayed as inspired by [Dionysus] into a state of ecstatic frenzy, through a combination of dancing and drunken intoxication. In this state, they would lose all self-control, begin shouting excitedly, engage in uncontrolled sexual behavior, and ritualistically hunt down and tear animals (and sometimes men and children) to pieces, devouring the raw flesh. During these rites, the maenads would dress in fawn skins and carry a thyrsus, a long stick wrapped in ivy or vine leaves and tipped by a cluster of leaves; they would weave ivy-wreaths around their heads, and often handle or wear snakes."
