"If there be room within, to stranger knight

  The castellain gives kindly welcome there:

  But is a lodging claimed by other wight,

  To joust with all new comers makes him swear:

  If none, he need not move; but arms and fight

  He must what stranger thither shall repair;

  And he that worst his warlike arms shall ply,

  Must wander forth beneath the naked sky.
