The serpent amazed the ancients with its strange qualities; it was 
sanctified in ancient Egypt, Greece, Rome, Mesopotamia and 
other countries. It was also associated with many Greek and 
Roman deities, for example Asclepius the god of medicine and 
his daughter Hygea the personification of healing and her Roman 
counterpart Salus, as well as the god Hermes, the messenger of 
the gods. The serpent was expressing the guardian spirit in the 
Greek religion and also the Roman, and there were known sorts 
of serpents in Greece that were protecting houses, so the Greeks 
opened their houses to host the serpents which considered the 
good or guardian spirits and called Agathodaimon, and the 
Agathodemon was mentioned for the first Once with Alexandria, 
where he was linked to the construction of the city and 
considered the guardian spirit of the city of Alexandria, also 
serpents associated with many Egyptian deities such as the 
goddess Wajit and others, some of them represent the good and 
others represent the evil.
