—Ultima VII, Part Two Bestiary
"Orcs are more annoying than dangerous to the seasoned adventurer, but they can be a grave threat to the novice, especially when they travel in large groups or accompanied by a giant or two. Generally, they are fairly easy to defeat, do a modicum of damage if they hit, and carry meager belongings." —Ultima V Bestiary
The six orcs above come from Vendel Miniatures (now sold by SGMM). I used my window sill studio to take this shot, augmented with a desk light. Usually, I paint the eyes, but for these I just used a black wash (watered-down acrylic) to fill in the recesses in the face.
Goblins, of course, have been a part of European folk lore for hundreds of years. J.R.R. Tolkein was the one who first popularized the term, "orc." It is thought that the word was ultimately derived from, orcus, Latin for "hell." Here's a well cited article discussing the etymology of the word on Wikipedia.
