The oldest sanctuary of Dionysus is near the theater. Within the precincts are two temples and two statues of Dionysus, the Eleuthereus (Deliverer) and the one Alcamenes made of ivory and gold. There are paintings here--Dionysus bringing Hephaestus up to heaven. One of the Greek legends is that Hephaestus, when he was born, was thrown down by Hera. In revenge he sent as a gift a golden chair with invisible fetters. When Hera sat down she was held fast, and Hephaestus refused to listen to any other of the gods save Dionysus--in him he reposed the fullest trust--and after making him drunk Dionysus brought him to heaven. Besides this picture there are also represented Pentheus and Lycurgus paying the penalty of their insolence to Dionysus, Ariadne asleep, Theseus putting out to sea, and Dionysus on his arrival to carry off Ariadne.

Pausanius Describes the Sanctuary of Dionysos

In the theater the Athenians have portrait statues of poets, both tragic and comic, but they are mostly of undistinguished persons. With the exception of Menander no poet of comedy represented here won a reputation, but tragedy has two illustrious representatives, Euripides and Sophocles. There is a legend that after the death of Sophocles the Lacedaemonians invaded Attica, and their commander saw in a vision Dionysus, who bade him honor, with all the customary honors of the dead, the new Siren. He interpreted the dream as referring to Sophocles and his poetry, and down to the present day men are wont to liken to a Siren whatever is charming in both poetry and prose. [2] The likeness of Aeschylus is, I think, much later than his death and than the painting which depicts the action at Marathon Aeschylus himself said that when a youth he slept while watching grapes in a field, and that Dionysus appeared and bade him write tragedy. When day came, in obedience to the vision, he made an attempt and hereafter found composing quite easy. [3] Such were his words. On the South wall, as it is called, of the Acropolis, which faces the theater, there is dedicated a gilded head of Medusa the Gorgon, and round it is wrought an aegis. At the top of the theater is a cave in the rocks under the Acropolis. This also has a tripod over it, wherein are Apollo and Artemis slaying the children of Niobe. This Niobe I myself saw when I had gone up to Mount Sipylus. When you are near it is a beetling crag, with not the slightest resemblance to a woman, mourning or otherwise; but if you go further away you will think you see a woman in tears, with head bowed down.
