she became subsequently, under that name, quite renowned in history. During the time in which these several transactions were taking place, various intrigues and contentions were going on among the governors of the different provinces in Europe and Asia, which, as the results of them did not particularly affect the affairs of Epirus, we need not here particularly describe. During all this period, however, Perdiccas was extending and maturing his arrangements, and laying his plans for securing the whole empire to himself; while Antipater and Ptolemy, in Macedon and Egypt, were all the time holding secret communications with each other, and endeavoring to devise means by which they might thwart and circumvent him. The quarrel was an example of what very often occurs in such political systems as the Macedonian empire presented at this time--namely, a combining of the extremities against the centre. For some time the efforts of the hostile parties were confined to the maneuvers and counter-maneuvers which they devised against each other. Antipater was, in fact, restrained from open hostility against Perdiccas from a regard to his daughter Nicæa, who, as has been already mentioned, was Perdiccas' wife. At length, however, under the influence of the increasing hostility which prevailed between the two families, Perdiccas determined to divorce Nicæa, and marry Cleopatra after all. As soon as Antipater learned this, he resolved at once upon open war. The campaign commenced with a double operation. Perdiccas himself raised an army; and, taking Philip and Eurydice, and also Roxana and her babe in his train, he marched into Egypt to make war against Ptolemy. At the same time, Antipater and Craterus, at the head of a large Macedonian force, passed across the Hellespont into Asia Minor, on their way to attack Perdiccas in Babylon. Perdiccas sent a large detachment of troops, under the command of a distinguished general, to meet and encounter Antipater and Craterus in Asia Minor, while he was himself engaged in the Egyptian campaign.
