BLAIR, John, a Scottish author, the contemporary and companion, some say the chaplain, of Sir William Wallace. He attended that illustrious hero in almost all his exploits; and, after his death, wrote Memoirs of the Scottish Champion, in Latin. But time has destroyed this work, which might have thrown great light on the history of a very troubled and remarkable period. An inaccurate fragment of it only has descended to us. It was published, with a commentary, in 1705, by Sir Robert Sibbald; and it is translated in Hume's History of the Douglasses.
