Dempster Thomas, a Scotchman of much miscellaneous erudition, was born at Muiresk, Aberdeenshire, about the year 1579. He studied at Cambridge, went to Paris, and obtained a temporary professorship in the College of Beauvais, where he manifested a very quarrelsome temper. He was afterwards professor at Pisa and Bologna, near which city he died, Sept. 6, 1625. Among his writings is a Historia Ecclesiastica Gentis Scotorum, "a work in which his desire to magnify the merits of his country often induced him to forge the names of persons and books that never existed, and to unscrupulously claim as Scotsmen writers whose birth-place was doubtful." — New Genesis Dictionary, 4:359.
