I hate it when authors add mythology/myths/folklore etc. into their stories and screw up the details. This time it's Greek Mythology, and I knew something was wrong when they started talking about Ophiuchus as the son of Apollo and Coronis, because here's the thing: these two never had a child named Ophiuchus.
Let's sort this out: Ophiuchus is not the actual son of Apollo and Coronis. Their son is named Asclepius, and his body was placed among the stars after his death, thereby creating the constellation Ophiuchus.
Ophiuchus = the constellation.
Asclepius = The son of Apollo and Coronis.
So can they stop talking about Ophiuchus like a person and use the right name? That'd be great, thanks.
