In Greek mythology, maenads were the female followers of Dionysus and the most significant members of the thiasus, the god's retinue.
Their name, which comes from μαίνομαι, literally translates as 'raving ones'. Maenads were known as Bassarids, Bacchae, or Bacchantes in Roman mythology after the penchant of the equivalent Roman god, Bacchus, to wear a bassaris or fox skin.

In Greek mythology and religion, the thiasus was the ecstatic retinue of Dionysus, often pictured as inebriated revelers. Many of the myths of Dionysus are connected with his arrival in the form of a procession. The grandest such version was his triumphant return from "India", which influenced symbolic conceptions of the Roman triumph and was narrated in rapturous detail in Nonnus's Dionysiaca. In this procession, Dionysus rides a chariot, often drawn by big cats such as tigers, leopards, or lions, or alternatively elephants or centaurs.
