mprise a number of bas-reliefs and rock
inscriptions, some of which were, beyond a doubt, set up by Sapor I. In
one of the most remarkable, the Persian monarch is represented on
horseback, wearing the crown usual upon his coins, and holding by the
hand a tunicked figure, probably Miriades, whom he is presenting to the
captured Romans as their sovereign. Foremost to do him homage is the
kneeling figure of a chieftain, probably Valerian, behind whom are
arranged in a double line seventeen persons, representing probably the
different corps of the Roman army. All these persons are on foot, while
in contrast with them are arranged behind Sapor ten guards on horseback,
who represent his irresistible cavalry. Another bas-relief at the same
place gives us a general view of Sapor on his return to Persia with his
illustrious prisoners. Here fifty-seven guards are ranged behind him,
while in front are thirty-three tribute bearers having with them an
elephant and a chariot. In the centre is a group of seven figures,
comprising: Sapor, who is on horseback in his usual costume; Valerian,
who is under the horse's feet; Miriades, who stands by Sapor's side;
three principal tribute bearers in front of the main figure; and a
_Victory_, which floats in the sky.

Another important work, assigned by tradition to Sapor I, is the great
dike at Shuster. This is a dam across the river Karun, formed of cut
stones, cemented by lime and fastened together by cramps of iron; it is
twenty feet broad and no less than twelve hundred feet in length. The
whole is a solid mass except in the centre, where two small arches have
been constructed for the purpose of allowing a part of the stream to
flow in its natural bed. The greater portion of the water is directed
eastward into a canal cut for it; and the town of Shuster is thus
defended on both sides by a water barrier, whereby the position becomes
one of great strength. Tradition says that Sapor used his power over
Valerian to obtain Roman engineers for this work; and the great dam is
still known as the "Dam of Caesar" to the inhabitants of the neighboring
country.

Sapor died, having reigned thirty-one years, from A.D. 240 to A.D. 271.
He was undoubtedly one of the most remarkable princes of the Sassanian
series. In military talent, indeed, he may not have equalled his father,
for though he defeated Valerian he had to confess himself inferior to
Odenathus. But in general governmental ability he is among
