Hmm, looking over some of the linked articles, I realize that Delicious in Dungeon takes a lot of its inspiration from real-world mythology as much as D&D bestiaries. It's fun going over the list to see which have featured in the show's recipes.
It's normally worth mentioning the Gorgon in these type of threads.
In Greek mythology, the term Gorgon referred to Medusa and her sisters. Snakes for hair, petrification, and all that. But in 1607, Edward Topsell wrote a bestiary that basically conflated the Gorgon with the catoblepas. For whatever reason, Gary Gygax based his Gorgon on the Topsell version rather than the Greek myth. As a result we still have bull-like Gorgons in D&D today.
