Relief with Snake-Bodied Deities. Romano-Egyptian, 30 BCE-100 CE. Two deities with human heads and serpent bodies intertwine their tails. They each wear a crown in the form of a grain measure, emphasizing their agrarian significance. The bearded figure on the left is probably Agathos Daimon (Good Demon), divine guardian of the city of Alexandria in Egypt, who was also associated with the god Serapis. The figure on the right is the goddess Isis in her manifestation as protector of the harvest, known as Thermuthis.
