Hello Isabel,
From The Athenian Agora, A Guide to the Excavation and Museum, American School of Classical Studies at Athens, 1976, p.50
The Temple of Hephaistos.......The excavations produced evidence of a formal garden around the temple in Hellenistic and early Roman times. Rows of rectangular pits bordering the north, south and west sides of the building contained flower pots for the setting out of shrubs or small trees. The garden has been replanted with pomegranate next the temple and myrtle in the outer rows. The flower pots are in the Museum.
If you ever happen to visit, please post pics.
Ther are a couple of old Thames and Hudson paperbacks on Attic vase painting by John Boardman. Copiously illustrated. You might find info about grapes and ivy. The olive harvesting by the Antimenes Painter is illustrated, also there is a scene of selling oil under a tree. Joanna
