In ancient Egypt, these amphibians were considered a symbol of resurrection and eternal life. Frogs were usually mummified with the deceased persons and buried with them in sepulcher, in order to help in their resurrection.

A frog was a symbol of the ancient Egyptian goddess Herit that assisted Isis to resurrect Osiris with the help of life-giving water. A frog is considered a chthonic animal and is endowed with abiogenesis capability. It is associated with the idea of creation and resurrection due to its cyclic way of life.
