"Thiasis" (often spelled thiasus or thiasos) is the frenzied, ecstatic retinue of the Greek god Dionysus, featuring maenads, satyrs, and spirits. This mythological procession symbolizes the untamed aspects of nature and wine. 


NOTE that women's roles as leaders in healing and comfort with focus on the process of maternity, switched to the Hellenistic and Roman views of mother and wife and medicine was put in the hands of males, changing the symbols of Asherah poles and to staffs for male chiefs and a sign of being the leader (Moses most notably and Zeus with his bolts of lightning).  This transformation seems to take place in all "religious" beliefs and practice, which was also influenced by Greek Philosophers.
