like the heads of lions; and fire, and smoke, and brimstone issued
from their mouths. By these three plagues the third part of men
was killed; by the fire, and by the smoke, and by the brimstone,
which issued from their mouths. For the power of the horses is in
their mouth, and in their tails: for their tails having heads were

suggests that they symbolize leaders of the four armies of the Tartars,
which successively overran the surrounding provinces. He says:

"The first horde were the Seljukians, who invaded the Eastern empire about
the middle of the eleventh century, under Togrul Beg. He suddenly overran,
with myriads of cavalry, the frontier, from Taurus to Arzeroum, and spread
it with blood and devastation. Alp Arslan, his successor, soon renewed the
invasion, conquered Armenia and Georgia, penetrated into Cappadocia and
Phrygia, and scattered detachments over the whole of lesser Asia. His
troops being subsequently driven back, he renewed the war, and recovered
those provinces. His descendants, and others of the race, soon after
extended their conquests, and established the kingdoms in the east of
Persia and Syria, and Roum, in lesser Asia, which they maintained through
many generations, and made their sway a scorpion scourge to the idolatrous
inhabitants. The Christians were allowed the e
