This is how I imagine Szarlej, a character from Andrzej Sapkowski's "Hussite Trilogy".
A philanthropist, skeptic, man of many talents, patron of the arts, polyglot, martial artist, scholar, war hero, good and loyal friend. Sounds too good to be true? Well, he has some bad sides, I admit, but I cannot dislike him. He's my favorite character of many other great people from the books.
