I've always loved Greek mythology but want to know more than just Wikipedia and pop culture. Any recommendations for websites, YouTube channels, books, etc. would be greatly appreciated!
Well, nothing beats reading Thomas Bullfinch, and for a visual equivalent of a webpage (but in book form) there's always D'Aulaire. Edith Hamilton is good too.
From Bullfinch and Hamilton you can go directly to the many sources, like Ovid or Euripides.
