Main Question or Discussion Point
I am almost finished with Griffiths intro to electrodynamics and was wondering what would be a good graduate level book on electrodynamics that I could self learn. I've also done His quantum mechanics book as well as Sakurai's quantum mechanics, and have a strong background in math (it's actually what my degree is in). My preference leans toward more mathematical rigorous books but that's just a preference any good book will do. Thanks.
