The Egyptian gods and goddesses were mostly anthropomorphic -- human shaped -- deities who behaved like humans and walked among mortals. Gods were not worshiped in the same way throughout Egypt or throughout time. Particular locations and pharaohs favored one set of gods over another. Here is a summary list of some of the major gods and goddesses of ancient Egypt and their primary functions.
Osiris, god of the dead, is the son of Geb and Nut, brother/husband of Isis, and father of Horus. He is dressed like the pharaohs wearing an atef crown with ram's horns, and carrying a crook and flail, with his lower body mummified. Osiris is an underworld god who after being murdered by his brother was brought back to life by his wife. Since he had been killed, Osiris thereafter lived in the underworld where he judged the dead.
Re, the Egyptian sun god, ruler of everything, was especially associated with the city of the sun or Heliopolis. He came to be associated with Horus. Ra may be depicted as a man with a sun disk on his head or with the head of a falcon
