Flint implements with rounded ends, excavated at several Upper Palaeolithic
sites in Denmark and Holland, are interpreted as strike-a-lights used in c
ombination with pyrites. Experimental flints employed int his way show use-
wear traces similar to those on the prehistoric specimens. It is suggested
that the pyrite technique for fire production predates wood-on-wood techniq
ues, at least in Europe and in Greenland.
