Lucifer

"The king of Babylon has the dubious distinction of sharing in Isaiah's oblique references to Satan, the one who has fallen from heaven" (F. LaGard Smith, The Daily Bible, p. 834).

“How you have fallen from heaven, O Lucifer, son of the morning!” (Isaiah 14:12; NKJV) 

Lucifer – heylel – (in the sense of brightness); the morning-star: KJV - lucifer (the king of Babylon)(Strong’s) 

Lucifer – light-bearer – the shining one, the morning-star, Lucifer; used of the king of Babylon and Satan (figuratively) (Brown Driver & Briggs Hebrew Lexicon)

See Isaiah 14:12-14; Ezekiel 28:11-19; Luke 10:18

  

Allusion: a reference, especially a covert, passing, or indirect one (Reader’s Digest Oxford Complete Wordfinder)

It would seem that this description of the king of Babylon is an allusion to Satan...
