    You need to understand some of the classical field theory before you enter its formal Lagrangian description; otherwise your formal knowledge will be quite empty regarding the physics.

    The third book in the Theoretical Minimum series by Leonard Susskind has appeared recently. It's about special relativity and classical field theory and may be the right trade-off between depth and learning time for you. It seems to include the Lagrange formalism for fields but I can't comment much on the actual contents because I haven't read it yet.

    Right. I should look into it. Thank you!
