or a natural death. As soon as they were invested with the bloody
purple, they inspired their adherents with the same fears and ambition
which had occasioned their own revolt. Encompassed with domestic
conspiracy, military sedition, and civil war, they trembled on the edge
of precipices, in which, after a longer or shorter term of anxiety, they
were inevitably lost. These precarious monarchs received, however, such
honors as the flattery of their respective armies and provinces could
bestow; but their claim, founded on rebellion, could never obtain the
sanction of law or history. Italy, Rome, and the senate, constantly
adhered to the cause of Gallienus, and he alone was considered as
the sovereign of the empire. That prince condescended, indeed, to
acknowledge the victorious arms of Odenathus, who deserved the honorable
distinction, by the respectful conduct which he always maintained
towards the son of Valerian. With the general applause of the Romans,
and the consent of Gallienus, the senate conferred the title of Augustus
on the brave Palmyrenian; and seemed to intrust him with the government
of the East, which he already possessed, in so independent a manner,
that, like a private succession, he bequeathed it to his illustrious
widow, Zenobia.

The rapid and perpetual transitions from the cottage to the throne,
and from the throne to the grave, might have amused an indifferent
philosopher; were it possible for a philosopher to remain indifferent

destructive to their subjects and adherents. The price of their fatal
elevation was instantly discharged to the troops by an immense donative,
drawn from the bowels of the exhausted people. However virtuous was
their character, however pure their intentions, they found themselves
reduced to the hard necessity of supporting their usurpation by frequent
acts of rapine and cruelty. When they fell, they involved armies and
provinces in their fall. There is still extant a most savage mandate
from Gallienus to one of his ministers, after the suppression of
Ingenuus, who had assumed the purple in Illyricum. "It is not enough,"
says that soft but inhuman prince, "that you exterminate such as
have appeared in arms; the chance of battle might have served me as
effectually. The male sex of every age must be extirpated; provided
that, in the execu
