prolog programming language

Prolog is another programming language I've tried. I have tried a line or two of sorce code in prolog and that is all. I wanted to learn prolog, but didn't follow threw with learning the language. I want to learn logic programming some day because I have no ideal what logic programming or prolog is or how to use prolog. As I have said before so many programming languages so little time to learn them, at least for me anyway.
