Analysis of On King Arthur's Round Table at Winchester

Where Venta's Norman castle still uprears
   Its rafter'd hall, that o'er the grassy foss,
   And scatter'd flinty fragments clad in moss,
   On yonder steep in naked state appears;
   High hung remains, the pride of war-like years,
   Old Arthur's board: on the capacious round
   Some British pen has sketch'd the names renown'd,
   In marks obscure, of his immortal peers.
   Though join'd by magic skill, with many a rhyme,
  The Druid frame, unhonour'd, falls a prey
  To the slow vengeance of the wizard Time,
  And fade the British characters away;
  Yet Spenser's page, that chants in verse sublime
  Those chiefs, shall live, unconscious of decay.
