Eros appears in ancient Greek sources under several different guises. In the earliest sources (the cosmogonies, the earliest philosophers, and texts referring to the mystery religions), he is one of the primordial gods involved in the coming into being of the cosmos. But in later sources, Eros is represented as the son of Aphrodite, whose mischievous interventions in the affairs of gods and mortals cause bonds of love to form, often illicitly. Ultimately, in the later satirical poets, he is represented as a blindfolded child, the precursor to the chubby Renaissance Cupid, whereas in early Greek poetry and art, Eros was depicted as an adult male who embodies sexual power, and a profound artist.
A cult of Eros existed in pre-classical Greece, but it was much less important than that of Aphrodite. However, in late antiquity, Eros was worshiped by a fertility cult in Thespiae. In Athens, he shared a very popular cult with Aphrodite, and the fourth day of every month was sacred to him (also shared by Herakles, Hermes and Aphrodite).
