“ HERMAE (ἑρμαῖ) , and the diminutive HERMULI (ἑρμίδια) , statues composed of a head, usually that of the god Hermes, placed on a quadrangular pillar, the height of which corresponds to the stature of the human body (ἡ τετράγωνος ἐργασία, Thuc. 6.27; τὸ σχῆμα τὸ τετράγωνον, Paus. 4.33.4) . Some difficulties are involved in the question of their origin, and of their meaning as symbols of Hermes. ”
