But, with a degree of virtuous resolution unexampled in history, he had
no sooner taken into his hands the entire reins of government, than he
renounced every vicious attachment. Instead of wallowing in luxury, as
before, he became a model of temperance; instead of cruelty, he displayed

Amongst those to whom this dreadful eruption proved fatal, was Pliny, the
celebrated naturalist, whose curiosity to examine the phenomenon led him
