I like this tutorial:

although it may be more advanced than what you are looking for. As for the
specific question you asked, apparently, the clause homem/1 is not defined
in your code, but is being specified as part of the man/1 clause. If you
don't understand what I just said, then you probably need to go back to a
good prolog book and read the first chapter. "The Art of Prolog" is always
a top candidate...

Good Luck!
