If you want a list of old-style gods, H. L. Mencken is a good starting place. See for example Funeral March: "Where is the graveyard of dead gods? ..."
"... Huitzilopochtli, like many other gods, had no human father; his mother was a virtuous widow; he was born of an apparently innocent flirtation that she carried on with the sun. When he frowned, his father, the sun, stood still. When he roared with rage, earthquakes engulfed whole cities. When he thirsted he was watered with 10,000 gallons of human blood. ...
"... Speaking of Huitzilopochtli recalls his brother, Tezcatilpoca. Tezcatilpoca was almost as powerful: He consumed 25,000 virgins a year. Lead me to his tomb: I would weep, and hang a couronne des perles. But who knows where it is? Or where the grave of Quitzalcontl is? Or Tialoc? Or Chalchihuitlicue? Or Xiehtecutli? Or Centeotl, that sweet one? Or Tlazolteotl, the goddess of love? Or Mictlan? Or Ixtlilton? Or Omacatl? Or Yacatecutli? Or Mixcoatl? Or Xipe? Or all the host of Tzitzimitles? Where are their bones? Where is the willow on which they hung their harps? In what forlorn and unheard of hell do they await the resurrection morn? Who enjoys their residuary estates? Or that of Dis, whom Caesar found to be the chief god of the Celts? Or that of Tarves, the bull? Or that of Moccos, the pig? Or that of Epona, the mare? Or that of Mullo, the celestial jack-ass? There was a time when the Irish revered all these gods ..."

... And so on. And so on.
Often people say, regarding their children, something along the lines of, "I don't want to tell them what to believe; I think they should be taught about different religions and then left to make their own minds up."
Similar thoughts are often expressed about R. E. in schools.
I'm still waiting for someone to mention Huitzilopochtli or any of the others in this regard.
I told my children the truth. Religions (plural) are nonsense - all of them. (Sometimes interesting nonsense, to be sure, but nonsense all the same.) We'd all be better off without them. My children grew up to be happy, successful, and - I dare assert - decent moral people who smile at the superstitious beliefs of theists (of all stripes).
