Note 571 — CANTO XX.

Michael Scott: Of Balwearie in Scotland, familiar to English readers through the Lay of the Last Minstrel. He flourished in the course of the thirteenth century, and made contributions to the sciences, as they were then deemed, of astrology, alchemy, and physiognomy. He acted for some time as astrologer to the Emperor Frederick II., and the tradition of his accomplishments powerfully affected the Italian imagination for a century after his death. It was remembered that the terrible Frederick, after being warned by him to beware of Florence, had died at a place called Firenzuola; and more than one Italian city preserved with fear and trembling his dark sayings regarding their fate. Villani frequently quotes his prophecies; and Boccaccio speaks of him as a great necromancer who had been in Florence. A commentary of his on Aristotle was printed at Venice in 1496. The thinness of his flanks may refer to a belief that he could make himself invisible at will.
