His words, like so many nimble and airy servitors, trip about him at command. Ibid.
Fairy damsels met in forest wide / By knights of Logres, or of Lyones, / Lancelot or Pelleas, or Pellenore.
On the tawny sands and shelves trip the pert fairies and the dapper elves.
Execute their airy purposes.
Fairy elves, / Whose midnight revels, by a forest side / Or fountain, some belated peasant sees, / Or dreams he sees, while overhead the moon / Sits arbitress.
