From The Golden Bough : A Study Of Magic and Religion
In Bithynia a like mournful ditty, called Bormus or Borimus, was chanted by Mariandynian reapers. Bormus was said to have been a handsome youth, the son of King Upias or of a wealthy and distinguished man. One summer day, watching the reapers at work in his fields, he went to fetch them a drink of water and was never heard of more. So the reapers sought for him, calling him in plaintive strains, which they continued to chant at harvest ever afterwards.
