MACEDONIA-SUCCESSORS OF ALEXANDER.
formidable antagonists, a foe still more to be dreaded appeared in
Pyrrhus, king of Epirus. With him he went to war, but on approaching the
borders of his adversary large bodies of the troops of Demetrius went
over to the enemy, and he was obliged not only to abandon the campaign,
but also to leave his own kingdom to the combined ravages of Pyrrhus and
Lysimachus. The Macedonian, however, continued the war in Asia Minor,

In these acts the venerable monarch was largely influenced by a desire
which had possessed him to revisit his native Macedonia. As soon as the

native hills, which he had not beheld for fifty-two years. Soon
afterwards, while with an old man's curiosity he was examining an
ancient altar, Ptolemy Ceraunus, who had accompanied him on his return
into Macedonia, stole behind and
