University of Chicago Excavations at
ISTHMIA
Head of Terracotta Figurine
"Ceramics in the construction fill [House X, Room A]... provide a date for the construction of the floor in Room A during the late 4th century or the first quarter of the 3rd. The terracotta figurine of a woman makes it likley that construction did not predate 300 B.C."
