This website has been my go-to for referencing and double-checking some historical or mythological knowledge. Because my novel is about aliens who learn from the gods who inhabited earth for a while, I like to make sure any symbolism or mention of any beliefs/philosophies linked to them are generally correct.
Here it is: Ancient History Encyclopedia
Part of my writer paranoia, even though I’m writing under the genre of science-fantasy, the most “what if this happened even though it’s not completely historical or practical” genre ever, is the fear of being called out on not portraying characters who I base off of mythology, history, folklore, or the like in a substantial or entertaining way. The greater majority of my characters are more original, but I have several mythology based characters I simply don’t want “out of character” or… “out of lore”. I don’t know what to call that. I don’t know. Maybe all of this is simply pagan paranoia. I don’t want to dishonor any deities or legends, fictional or not.
If anyone has any other sources, feel free to share.
