Raw sulphur was used by people called Saami (Scandinavia) in small spoon (svavelslev) like a tinder. Also used on tip of wooden sliver like a modern match.
I don´t know how exactly it was used, but I do it so. I catch spark into tinder (charred cloth or fomes fomentarius), then put it to sulphur and by blowing make a small fire. Then extend it with small strip of birch bark. Good luck, friends.

i got some natural sulfur crystals from a mineralogist friend and, considering that sulfur is a component of gunpower, and also i'd read that eskimos once rubbed sulfur onto quartz crystals before banging them together flint-and-steel-style to get sparks, i decided to throw some flint-and-steel sparks onto the sulfur to see if anything would happen. Poof! bluish-purple flames appeared! i ground the sulfur up, but noticed that the larger pieces (2-3mm) were the ones that flamed up first.

And speaking of which, Lord Avebury in his book "Prehistoric Times, As illustrated by Ancient Remains and the Manners and Customs of Modern Savages" Publisher, Williams & Norgate, London 1913, tells of Eskimos in NW Alaska making fire using two pieces of quartz. One piece is rubbed in sulfur and struck with the second piece. Other Eskimos near Hudson Bay I believe it was, struck iron pyrites with flint like we do with steel.
