In the early years of the tenth century a.d. the Emperor Leo VI, surnamed the Philosopher, gave much scandal to the ecclesiastics of Constantinople by his fourth marriage with the beautiful Zoe; a fourth being naturally a degree worse than a third marriage, and this the Eastern Church had lately “censured as a state of legal fornication,” for reasons which Gibbon discusses in chapter xlviii of the “Decline and Fall” However, “the Emperor required a female companion, and the Empire a legitimate heir,” and so, since he had found himself again a childless widower, Leo the Philosopher promptly celebrated his fourth nuptials, the patriarch Nicholas notwithstanding, who, having refused his blessing, was exiled. The fruit of this marriage was Constantine, surnamed Porphyrogenitus, that is, Born-in-the-Purple, from the porphyry chamber in the palace at Constantinople, where he had first seen the light; and in the year 911 a.d., when of the age of six, Constantine VII succeeded his father on the throne.
