It is very doubtful if they believed in the existence of one supreme God, as most of the heathen did; but if they did, "they did not under any form, symbol, or hieroglyphic, represent the idea of the unity of God," as is fully proved by Wilkinson.[50] On the contrary, the monuments confirm the satirical sketch of the poet,[51] as to the "monsters mad Egypt worshiped; here a sea-fish, there a river-fish; whole towns adore a dog.
This place fears an ibis saturated with serpents; that adores a crocodile.

It is a sin to violate a leek or onion, or break them with a bite." Cruel wars were waged between different towns, as Plutarch tells us, because the people of Cynopolis would eat a fish held sacred by the citizens of Latopolis.

Bulls, and dogs, and cats, and rats, and reptiles, and dung beetles, were devoutly adored by the learned Egyptians.

A Roman soldier, who had accidentally killed one of their gods, a cat, was put to death for sacrilege.[52] Whenever a dog died, every person in the house went into mourning, and fasted till night.

So low had the "great, the mighty and transcendent soul," been degraded that there is a picture extant of one of the kings of Egypt worshiping his own coffin! Such is man's knowledge of God without a revelation from him.
The Greeks, from their early intercourse with Egypt, borrowed from them most of their religion; but by later connections with the Hebrews, about the time of Aristotle and Alexander, they gathered a few grains of truth to throw into the heap of error.
