Thomas Learmonth (c. 1220[1] – c. 1298;[2] also spelled Learmount, Learmont, or Learmounth), better known as Thomas the Rhymer or True Thomas[3], was a 13th century Scottish laird and reputed prophet from Earlston (then called "Erceldoune"). He is also the protagonist of the ballad "Thomas the Rhymer" (Child Ballad number 37).[4] He is also the probable source of the legend of Tam Lin.
