Sesen is the lotus flower that appears so often in Egyptian art and symbolizes life, creation, rebirth and, especially, the sun. The symbol dates from the beginning of the dynastic period, but it became more popular from the Old Kingdom. The lotus flower closes at night and sinks in the water; then, at dawn, it opens again; this pattern identified him with the sun and, therefore, with life.
The flower also represented rebirth for the same reason and was associated with the god Osiris. The Four Sons of Horus, regularly depicted in canopic bottles, are often depicted together in a lotus in the presence of Osiris. The lotus flower appears in many different types of Egyptian art, from stoneware statues to sarcophagi, temples, shrines and amulets. It was the symbol of Upper Egypt, since the papyrus plant symbolized Lower Egypt and the flower is sometimes depicted with its stem intertwined with that of the papyrus plant
