On the main side of stamnos, there is a scene of a dionysiac festival, probably Lenaia. In the center of the image, there is the cult statue (xoanon) of Dionysus. It consists of a tree-trunk, which stands on a plinth and has on top a mass of ivy leaves. A mask and garments are hanging on the xoanon. The god has long hair and beard. He wears an ivy wreath, long chiton, and himation. In front of him, there is a table with various offerings (cakes or slices of meat). Two women are depicted to the right and left of the god's statue, probably Maenads. Both wear long chitons, himatia and ivy wreaths. The woman to the left holds a kantharos (ritual drinking cup) and a thyrsus (stick that ends in a pinecone with ivy and vine leaves), and the second woman to the right holds an oinochoe and a kanoun (wicker basket) with sacrificial offerings.

Lenaia are derived etymologically from the word Lénai or Lenaí («Λῆναι» or «Ληναί»), which refers to Bacchai, the followers of Dionysus. It is an Athenian festival that included processions, dramatic competitions and jokes (skommata).
