born ugly is actually incorrect. Medusa was beautiful and even was in a secret relationship with Poseidon until Amphitrite found out and cursed her with her ugliness.
Nice quiz but there is a lot of room for improvement. I don't get the hint for Ajax (but maybe that's on me). Chimaera should be accepted. You confused Cronus/Kronos with Chronus. Nemean Lion is misspelled. And Janus does not occur in Greek mythology, only Roman. And there are probably more things, which I missed.
Also Delphin was not a god he was an acutal dolphin who aided Posiedon in the search for Amphitrite and she couldn't resist such an amazing creature and she allowed him to take back to Poseidon and marry him becoming queen of the sea and Delphin the dolphin was honored by Poseidon and turned into the constellation Delphinus.
Sisyphus was the cleverest man alive as he managed to capture death and cheat death. Daedalus was known as being the father of Icarus and crafter of the labyrinth wich housed the minotaur
A lot of the clues were pretty vague, it seems like you got a lot of things from PJO which is pretty inaccurate, and I think maybe you can learn to spell?
there weren't any mention of dragons or hellhounds in classic mythology the only dogs in greek mythology were Orthorus the two headed dog guardian of Geryon's cattle and Cerbeus the three headed guardian of the gates of Hades. Also Sisyphus was the cleverest man of ancient Greece as he imprisoned and cheated death. Daedalus was known as the greatest inventor designer of the labyrinth and father of Icarus who fell from the sky. Medusa actually had two gorgon sisters Euryale, and Stheno and she was born human. She was devoted to the goddess Athena since childhood and even rejected the love of her childhood friend Iphecles saying she wanted to be an Athena priestest. Acutally it is believed that even as a gorgon she took refuge in an abandoned Athena temple and continued her rituals and Athena genually felt regret over inflicting a cruell and irreversable punishment on one who was devoted to her. When she gave the shield to Perseus she actually wanted her to be free from this curse.
e.g. it was frustrating that hyperboreans was not accepted because hyperborean giants was expected
Many mis-spelled words with no acceptance of anything not verbatim.
Terrible.
