A Greek statue common during the 4th century BC. Hermai consist of a head on top of a four sided plain pillar with the exception of a phallus in the center. At the University of Chicago, students created ice sculptures of the Hermai and placed them throughout campus as a prank.
"What is that ice sculpture with a huge penis!"-Ari
"That is a replica of a Hermae, common in ancient athens during the Peloponnesian War."- Peter
