Dionysos is the god of wine for the Greeks and Romans. His festivals were known as the Dionysian festivals. These festivals consisted of ceremonies where the participants carried receptacles filled with wine and wore diadems of grape branches.
There were small and large Dionysian festivals. In such festivals tournaments were organized for swimming, wrestling and other sports. Poetry and drama were also part of these festivals. Through such festivals the cult of Dionysos was introduced into the Greek religion in the Late Period.
The cult of Dionysos was added later to the cult of the great Greek gods. It seems that the cult of Dionysos was imported from Asia or Egypt. Most probably, his cult appeared in the province of Attica in the ninth century BC. The cult of Dionysos was mentioned four times by Homer in the Iliad.
Also, some literary resources refer to Dionysian temples in the province of Attica that are dated between the eighth and ninth centuries BC. In Egypt, grapes and their juice were important as they became symbols of Christ.
