   applied in Isaiah by a metaphor to a king of Babylon.
         How art thou fallen from heaven, O Lucifer, son of
         the morning ! how art thou cut down to the ground
         which didst weaken the nations !      --Is. xiv. 12.
         Tertullian and Gregory the Great understood this
         passage of Isaiah in reference to the fall of Satan;
         in consequence of which the name Lucifer has since
         been applied to, Satan.               --Kitto.
2. Hence, Satan.
         How wretched Is that poor man that hangs on princes'
