Spanish scholar and scribe of the thirteenth century. He wrote a Spanish treatise on the preparation of gold-foil and colors for miniatures; also a treatise, probably in Hebrew, on the Masorah and on the crowned letters in the scroll of the Pentateuch (De Rossi, "Cat. Parma," No. 945). Steinschneider ("Jewish Literature," p. 328, note 53) identifies Ibn ?ayyim with Abraham ben ?ayyim, the French liturgist; but, according to De Rossi ("Dizionario," 1:6), Ibn ?ayyim wrote his first treatise in Spanish.
