[108] The _Mappae Clavicula_ (Key to Painting) belongs to the tenth century; the _Compositiones ad Tingenda_ is of the age of Charlemagne. A MS. of the eighth century (not the ninth as Berthelot says) is extant at Lucca (Bibl. Capit. Can. I. L.). Muratori has printed it in his _Antiquitates Italicae_, ii. 364-87. It contains receipts for the colours used in making _tesserae_ for mosaic, for dyeing skins, cloth, bone, horn and wood; for making parchment; for various processes such as gold and silver beating and drawing, and the gilding of iron; for chrysography and the gilding of leather; ‘quomodo eramen in colore auri transmutetur,’ ‘operatio Cinnaberim,’ a perfume for the hands called _lulakin_, and for certain amalgams of gold and silver called _glutina_. [109] See Chwolson, _Die Ssabier und der Ssabismus_. The Egyptians extended this correspondence to the members of the human body.

My copy is the one presented by the author to the great Aldrovandus of Bologna, with whom he seems to have been on intimate terms. [112] See the Paris MS. 6514, pp. 133-35.

This treatise is the same as the _De mineralibus_ published along with the _De Secretis_ at Venice (? 1501) by Bernardinus de Vitalibus. [116] Speciale MS. No. vi. See the work by Sac. I.

Eighty thousand books are said to have been burned in the squares of Granada alone. [118] In the editions of 1622 and 1659, Argentorati. It has been stated that the _Quaestio Curiosa_ is a chapter taken from the _Liber Introductorius_ of Michael Scot. The alternative title of that work, _Judicia Quaestionum_ would seem to favour this idea, and may in fact have suggested it. But an examination of the _Liber Introductorius_ (MS. Bodl. 266), which I have caused to be made, proves that the statement referred to is without foundation. It was advanced in a paper read before the Scottish Society of Antiquaries by Mr. John Small, and printed in their _Proceedings_, vol. xi. p. 179. [119] See the note to p. 75 _supra_.

Florence, where this treatise is given to _Alfidius_, _i.e._ Al Kindi. In it occur the significant words: ‘est (alchimia) de illa parte physice quae _Metheora_ nuncupatur.’
