Ethiopians say that their gods are snubnosed and black Thracians that they are pale and red-haired. - Xenophanes

There is one god, greatest among gods and men, similar to mortals neither in shape nor in thought.

One day a dog was being thrashed in the street,
and behold, Pythagoras, philosopher of spirits,
was walking by.
His heart was in his mouth
for the poor pup.
'Stop! Stop!' he cried.
'Don't beat him any more.
This is my dear friend's soul.
I recognize the voice when I hear him bark.

ἀλλ᾽οἱ βροτοὶ δοκέουσι γεννᾶσθαι θεοὺς,
τὴν σφετέρην δ᾽ἐσθῆτα ἔχειν φωνήν τε δέμας τε.
