and the Fair Annet or Elinor, had a lovers quarrel, when Lord Thomas resolved to forsake Annet for a nut-brown maid who had houses and lands. On the wedding-day Annet, in bridal bravery, went to the church, when Lord Thomas repented of his folly, and gave Annet a rose. Whereupon the nut-brown maid killed her with a long bodkin from out her gay head-gear. Lord Thomas, seeing Annet fall dead, plunged his dagger into the heart of the murderess, and then stabbed himself. Over the graves of Lord Thomas and fair Annet grew a bonny briar, and by this ye may ken right well that they were lovers dear. In some ballads the fair Annet is called the fair Elinor.
