CHAP. 50. (15.)—SULPHUR, AND THE SEVERAL VARIETIES OF IT:
FOURTEEN REMEDIES.
Let thus much be deemed sufficient on the subject of bricks.
Among the other kinds of earth, the one of the most singular
nature, perhaps, is sulphur, an agent of great power upon other
substances. Sulphur is found in the Æolian Islands, between
Sicily and Italy, which are volcanic, as already
1 stated. But
the finest sulphur of all, is that which comes from the Isle of
Melos. It is obtained also in Italy, upon the range of hills in
the territories of Neapolis and Campania, known as the Leucogæi:
2
when extracted from the mines there, it is purified by
the agency of fire.
There are four kinds of sulphur; the first of which is "live"
sulphur, known as "apyron"
3 by the Greeks, and found in solid
masses, or in other words, in blocks. This, too, is the only sulphur
that is extracted in its native state, the others being found in a
state of liquescence, and requiring to be purified by being boiled
in oil. This kind is green and transparent, and is the only
sulphur that is used for medicinal purposes. A second kind is
known as the "glebaceous"
4 sulphur, and is solely employed in
the workshops of the fullers. The third kind, also, is only used
for a single purpose, that of fumigating wool, a process which
contributes very greatly to making the wool white and soft;
"egula"
5 is the name given to it. The fourth kind is used
in the preparation of matches more particularly.
In addition to these several uses, sulphur is of such remarkable
virtue, that if it is thrown upon the fire it will at once
detect, by the smell, whether or not a person is subject to
epilepsy. Anaxilaüs used to employ this substance by way
of pastime: putting sulphur in a cup of wine, with some
hot coals beneath, he would hand it round to the guests, the
light given by it, while burning, throwing a ghastly paleness
like that of death upon the face of each. Its properties are calorific
and maturative, in addition to which, it disperses abscesses
on the body: hence it is that it is used as an ingredient in
plasters and emollient poultices. Applied to the loins and
kidneys, with grease, when there are pains in those parts, it
is marvellously effectual as a remedy. In combination with
turpentine, it removes lichens on the face, and leprosy,
6 the
preparation being known as "harpax,"
7 from the celerity
with which it acts upon the skin; for which reason it ought to
be removed every now and then. Employed as an electuary, it is
good for asthma, purulent expectorations, and stings inflicted
by scorpions. Live sulphur, mixed with nitre, and then bruised
with vinegar and applied, causes morphew to disappear, and
destroys nits in the hair; in combination, too, with sandarach
and vinegar, it is good for diseases of the eyelids.
Sulphur has its place among our religious ceremonies, being
used as a fumigation for purifying houses.
8 Its virtues are
also to be perceived in certain hot mineral waters;
9 and there
is no substance that ignites more readily, a proof that there is
in it a great affinity to fire. Lightning and thunder are attended
with a strong smell of sulphur, and the light produced
by them is of a sulphureous complexion.
