A copy of Johannes de Rupescissa, De consideratione quintae essentiae, in Latin, written by two cursive Gothic hands on paper in Italy in the late 15th century.
Contents
1. ff. 1-15v, 15v-23r, 25r-26v: Johannes de Rupescissa (Jean de Roquetaillade), De consideratione quintae essentiae, Books 1-2, in Latin.
The treatise, probably written by Rupescissa about 1351-1352, describes the alchemical processes for the extraction by distillation of the essence of wine, plants and minerals for medicinal purposes. The distillation of the aqua ardens (ethyl alcohol) extracted from wine is at the basis of all the other processes described. The author believes the alcohol to be an element similar to the so-called quinta essentia, the incorruptible fifth element that according to Aristotle forms the essence of heavenly bodies, and is therefore capable of preserving the human body from corruption and illnesses. The text is divided into two books, the first dedicated to the distillation processes with subdivisions called canones, the second to the medical applications of the essences described, organised in chapters called remedia.
The text is listed in eTK, A digital resource based on Lynn Thorndike and Pearl Kibre, A Catalogue of Incipits of Medieval Scientific Writings in Latin (Cambridge, MA: Mediaeval Academy, 1963; with supplements in 1965 and 1968; online at https://medievalacademy.site-ym.com/?page=Books#etk), no. 458A.
Printed for the first time as Ioannis de Rupescissa qui ante CCCXX annos vixit de consideratione quintae essentiae rerum omnium, opus sane egregium (Basel, [1561]) by Guillaume Gratarolo, with his dedicatory letter dated 1561. The publication also included Arnaldus de Villanova, Epistola de sanguine humano distillato, Raymundus Lullus, Ars operativa et alia quaedam and Michael Savonarola, Libellus optimus de aqua vitae.

The text of Book 1 was assembled in two stages: the first quire (ff. 1-8) included the Canons 1-4 and 13, but only the text of Canon 1 had been copied in full. The text portions missing in Canons 2-4 and 13 were supplied by a second hand on an additional leaf after f. 8 (on f. 9r), and on ff. 10r-15v in quire 2 and ff. 25r-26v in quire 3 at the end of the volume. Consequently, with portions of text totally out of sequence, the correct sequence of Book 1 is as follows: Canon 1 on ff. 1r-3v; Canon 2 on ff. 3v-5r and 25r (last two chapters 'Scientia diversitatis habendi quinta essentia / Modus primus et omnium principalius ' and 'Magisterium autem separatione vinum ab alia mirabile et ingeniosum est istud / Recipe stillum ferreum acutum'); Canon 3 on ff. 5r-5v and 25r-v (chapter 'Scientia extractionis quintae essentiae ab omnibus fructibus foleis radicibus et herbis / Est aliud ex secretis naturae '); Canon 4 on ff. 25v-26r (first chapters) and 5v, last line-6r (last chapter 'Scientia ad fortius et uiuacius ad imprimendum virtutes solis in celo nostro / Et in hoc loco decreui reuellare ingenium'); Canons 5-12 on ff. 10r-15v, line 14; Canon 13 on ff. 6v-9r and 26r-v.
f. 15v, line 15, Book 2: Title [underlined in red]: Incipit liber secundus qui de generalibus remediis appellatur; Incipit: Licet primus liber qui est de consideratione .D. tante virtutis in rei veritate existat ut per ipsum possit curare omnis morbi curabilis ...

2. f. 9v: Additional alchemical recipes, in Latin, seemingly not identifiable in Johannes de Rupescissa, De consideratione quintae essentiae: a)pro lib .1. istius aque 2/j in anime vini et congelasiones scis lento igne ...; b) Item si vis dissolvere super dictos calces in aqua cum conseruatione sua ...; c) Recipe vinum veterum rubeum vestris anni vel vinum album optimum ... Distillatorium debet inpleri usque ad duas partes et 3 pars debet remanere vacua causa vapori faciendi et ita dicitura perfecta ipsa distillationis; d) Jtem ad faciendum aquam vitae siue ardentis / Recipe duas libras salis ... eam coligimus [?].
3. ff. 23v-24r: Alchemical process to obtain gold, in Latin, unidentified.

6. ff. 26v-27r: Six medical receipts supplied in Spanish by several 16th century hands: a) 'Y tomaras la yeruce ; b) 'para orinar'; c) 'recipe calzina biba'; d) 'tomaras aqua poistada'; e) 'para les barbes'; f) 'para los renyse'.
7. f. 27r: Invocation within a square frame: 'his manuel. Ysach. His rrael [or srael]'.
This manuscript was originally part of a larger volume containing MSS 443 [Lullius] and 444 [Lullius], as is proved by the identity not only of the main script, but also that of the several 16th-century added medical receipts in Spanish, and by the oldest foliation '12-37' in the upper right edge of rectos finding correspondence with a similar foliation in the two other manuscripts.
A typescript description of the manuscript in French inserted at the beginning, 20th century.
Marked '3025' in pencil on upper pastedown, 20th century.
