Note 275 — Chapter IX · THE LEGEND OF MICHAEL SCOT

Leonardo Pisano uses this word in the Liber Abbaci. See p. 187vo of the Florence MS. Bibl. Naz. i. 2616, where the following passage occurs: ‘Secundum modum algebrae et almuchabalae, scilicet ad proportionem et restaurationem.’ In an ancient list of works by Gerard of Cremona (? the younger) found in the Vatican (No. 2392) we have this title: ‘Liber alcoarismi de iebra et almucabala tractatus.’ See Boncompagni’s Life of Gerard, Rome 1851. Works on almuchabola are found also under the names of Al Deinouri, Al Sarakhsi, Al Khouaresmi, Khamel Schagia ben Aslam, and Al Thoussi. See D’Herbelot.
