The shading here seems deliberately suggestive of Milton's Satan. From the very first,
                     the Satanic legions sense that the fall from heaven has diminished their spiritual
                     essence, and, as in these early words of Satan's chief follower Beelzebub, that loss
                     is expressed in terms of "glory." 
the mind and spirit remains 
 Invincible, and vigour soon returns, 
 Though all our glory extinct, and happy state 
 Here swallowed up in endless misery. (I.139-42) The most resonant identification
                     of diminished glory with the fall of the angels is uttered by Satan as he soliloquizes
                     atop Mount Niphates at the opening of Book IV. There, as he addresses the Sun, the
                     fallen archangel directly contrasts himself and God in terms of their manifestation
                     of glory. 
 O thou, that, with surpassing glory crowned, 
 Lookest from thy sole dominion like the God 
 Of this new world; at whose sight all the stars 
 Hide their diminished heads; to thee I call, 
 But with no friendly voice, and add thy name, 
 O Sun! to tell thee how I hate thy beams, 
 That bring to my remembrance from what state 
 I fell, how glorious once above thy sphere; 
 Till pride and worse ambition threw me down 
 Warring in Heaven against Heaven's matchless King. (IV.32-41)
