The torches probably contained the elements mentioned in the form of a mixture of free sulphur and calcium sulphate, which is still to be found in Italy. A torch of this composition, if burning well, would not be extinguished by a brief or partial immersion in water, so that the Bacchanals could perform the feat mentioned if they were reasonably swift in their movements. Calcium sulphate will not burn; free elementary sulphur burns, and we should probably translate
vivum as
free
or
elementary
and therefore
burnable.
But it is rather remarkable that Livy, who was not a scientist, should have approached scientific fact so closely. I am indebted for this information to Dr. E. Ward Tillotson, Assistant Director, and Dr. W. W. Duecker, Senior Industrial Fellow, both of the Mellon Institute of Industrial Research of the University of Pittsburgh.
