BLAIR, John, a Scottish author, was contemporary with, and the companion, some say the chaplain, of Sir William Wallace. He attended that great hero in almost all his exploits: and, after his death, which left so great a stain on the character of Edward I. of England, he wrote his memoirs in Latin. The injury of time has destroyed this work, which might have thrown the greatest light on the history of a very busy and remarkable period. An inaccurate fragment of it only has descended to us, from which little can be learned, and which was published, with a commentary, by Sir Robert Sibbald.
