Pausanias, Description of Greece 3.13.7
Nearby is the temple of Dionysos Kolonates (of the Knoll), by which is a precinct of the hero who they say guided Dionysos on the way to Sparta. To this hero sacrifices are offered before they are offered to the God by the daughters of Dionysos and the daughters of Leukippos. For the other eleven ladies who are named daughters of Dionysos there is held a footrace; this custom came to Sparta from Delphoi.
