An excerpt from Grinstead and Snell's Introduction to Probability, page 110:

"The first appearance of Pascal’s triangle in the West seems to have come from calculations of Tartaglia in calculating the number of possible ways that n dice might turn up. For one die the answer is clearly 6.... The problem had suggested itself to Tartaglia from watching people casting their own horoscopes by means of a Book of Fortune, selecting verses by a process which included noting the numbers on the faces of three dice."

So it appears that people were rolling 3d6 back in 1523, centuries before Steve Jackson "invented" GURPS. Whatta rip-off, Steve. You're stealing ideas from Tartaglia for God's sake. Hasn't that man suffered enough?
