House of Hades-Character Symbols

In the book, The House of Hades, all the characters can be very well represented by different symbols. Especially the gods and titans because in greek mythology, they had specific symbols that they made for them. For example, Zeus's symbol was an eagle. Or Poseidon's symbol was a trident. But in this book Rick Riordan does a great job of setting a symbol for each demigod, you just have to infer what it is. The main character, Percy Jackson, is the son of Poseidon and is really good at sword fighting, so his symbol would his sword; Riptide. Another main character is Jason, who is the son of Zeus, so his symbol could be a lighting bolt. Another demigod is Annabeth, who is the daughter of Athena so her symbol could be an owl. A symbol representing gods during greek times was also a tradition, so many people did it.
