D&D is shaped by the mythologies we are exposed to - both ancient and modern. With the explosion of fantasy and science-fiction books in the modern era, some of the traditional archetypes are changing.
One way of examining that is to guess what classes the characters from Literature and Legend are in terms of the D&D rules system. Of course, many of them will be approximations, but that's ok.
I'm particularly interested in multi-class spellcasters, so I'll begin with a few of those:
Rand al'Thor - Fighter/Sorcerer - Wheel of Time by Robert Jordan
Richard Rahl - Ranger/Sorcerer - Sword of Truth by Terry Goodkind
Ingold Inglorion - Fighter/Wizard - Darwath Trilogy by Barbara Hambly
Vlad Taltos - Rogue/Sorcerer/Wizard/Assassin - Taltos series by Steven Brust
Although there are quite a few such multiclasses, one can also see a great number of single classed characters and other non-spellcasting characters.
Perrin - Expert/Fighter - Wheel of Time by Robert Jordan
Mat - Rogue/Fighter - Wheel of Time by Robert Jordan
Kahlan - Confessor* Expert - Sword of Truth by Terry Goodkind
Zedd - Wizard - Sword of Truth by Terry Goodkind
Gil Shalos - Expert/Fighter - Darwath Trilogy by Barbara Hambly
Rudy - Wizard - Darwath Trilogy by Barbara Hambly
Kahlan is interesting - in effect, she has racial abilities due to her Confessor heritage. Heritage can play a large part in determing magical abilities - so that the elvenkind are often innately magical whilst their class is straight fighter or rogue...
Modern Fantasy also gives us telepaths like the Heralds of Valdemar - probably best handled by a Psychic Warror/Paladin hybrid class.
Actual mythology - of the Greek kind - gives us fighters, more fighters, perhaps a rogue or two, and if you're very lucky, a blind seer. Priests are known for their ability to curse (see the cause of the Wrath of Achilles), but not so much for curative powers.
Cheers!
