This manuscript contains texts related to medicine or alchemy, all attributed to Ramon Llull, a Catalan philosopher who lived from around 1235 to around 1315. Many alchemical works were misattributed to Llull in the late Middle Ages and the Renaissance, including those in this manuscript. The versions of these texts included in this manuscript were written around 1525 and the hand seems to be Italian, but a colophon on f. 128v states that it was written by Franciscus de Galliciis, which might refer to Galicia in Spain. The contents are as follows:

Back of original fly-leaf: List of contents

f. 1r: Extract from Ars operativa medica by Pseudo-Llull

ff. 2r-128v: Liber de Secretis Naturae Seu de Quinta Essentia by Pseudo-Llull

ff. 129r-141r: De Medicinis Secretissimis or Medicina Magna by Pseudo-Llull

f. 141v: Recipe ad Stillandum aurum potabile (recipe to obtain potable gold) by Pseudo-Llull

The texts are described separately under MS 122/f. 1r; MS 122/ff. 2r-128v; MS 122/ff. 129r-141r; and MS 122/f. 141v.

A fair hand, with no attempt at ornament save plain red capitals and diagrams in Book Four, which are careful and elaborate.

The first section (f. 1r) and the third and fourth sections (ff. 129r-141v) seem to be in a slightly different hand to the second section (ff. 2r-128v), but they are similar. There are some notes and annotations in another hand throughout.
