Cista mystica with serpent; all within ivy wreath / Bow-case with serpents, monogram to left, AM above, snake-entwined staff to right. SNG France 5, 1716; SNG von Aulock -. VF. A Dionysiac ivy wreath surrounds the cista mystica or "mystic basket", which held the sacred serpent carried by young girls of high rank at public festivals and feasts in celebration of the mystic rites of Dionysos, a divinity particularly honoured by the kings of Pergamon. The reverse quiver was a symbol of Herakles. The serpents were symbols of the king because of their power, of time because of their length, and of rebirth or renewal, because of the shedding of their skins. Serpents played a central part in the mysteries of Dionysos in their role as protectors of the vine (by eating mice and other consumers of grapes).
