Abridged comment… On this ship, I epitomize from MoM 2§115 (where I give further references):
On the occasion of the spectacular quadrennial parade known as the Panathenaic Procession, the peplos or ‘robe’ of Athena was displayed as an archetypal Sail rigged to the mast of a float that re-enacted the archetypal Athenian Ship of State; this float was rolled on wheels along the Sacred Way, from the Kerameikos through the Agora, all the way to a sacred space known as the Eleusinion (scholia for Aristophanes Knights 566).
