Arsenal 1036, 14th century, fol. 104v.
Dijon 1045, 15th century, fol. 81-.
Other MSS containing Experiments of Albumasar but where I am not sure of the wording of the Incipit are:
Laud. Misc. 594, 14-15th century, fol. 123-, Liber experimentorum.
Harleian 1, fols. 31-41, de experimentis in revolutione annorum mundi.
CLM 51, 1487, and 1503.
Vienna 2436, 14th century, following John of Spain’s translation of the Introductorium magnum at fols. 1-85 and a Liber magnarum coniunctionum at fols. 144-98, comes at fol. 242, “Liber experimentorum seu Capitula stellarum oblata regi magno Sarracenorum ab Albumasore.” The Incipit here is “Dispositio est ut dicam ab ariete sic initium” but the treatise is incomplete.
In some MS at Oxford which I cannot now identify the Flores of Albumasar close with the statement that the book of Experiments will follow. A different hand then adds “The following work is Albumazar on the revolutions of years,” while a third hand adds the explanation, “And according to some authorities it and the book of experiments are one,” which is the case.
In some MSS, however, another treatise on revolutions accompanies the Experiments. In Amplon. Quarto 365 it is followed at fols. 18-27 by Sentencie de revolucione annorum, while in Laud. Misc. 594 it is preceded at fol. 106 by Liber Albumasar de revolutionibus annorum collectus a floribus antiquorum philosophorum, which is the same as the Flores.
[2615] The distinction between these various works is made quite clear in BN 16204, 13th century, where at pp. 1-183 is John of Spain’s translation of the Liber introductorius maior in eight parts; at 183-302 the Conjunctions, also in eight parts; at 302-333 the Revolutio annorum mundi or Liber experimentorum; at 333-353 the Flores, and at 353-369 the De revolutione annorum in revolutione nativitatum, which opens “Omne tempus breve est operandi....” At the same time the Explicit of this treatise bears witness to the ease with which these works of Albumasar are confused, for it was at first written, “Explicit liber albumasar de revolutione annorum mundi,” and some other hand has crossed out this last word and substituted “nativitatis.”
