On the Death of George, Athanasius returns to Alexandria, and takes Possession of his See
Not long after this, Athanasius returning from his exile, was received with great joy by the people of Alexandria. They expelled at that time the Arians from the churches, and restored Athanasius to the possession of them. The Arians meanwhile assembling themselves in low and obscure buildings, ordained Lucius to supply the place of George. Such was the state of things at that time at Alexandria.
