Could the manuscript that is now Linköping Library, Kl. f. 10 be what remains of a lost codex from the Escorial library, namely Scorial. H. V. 3?
Linköping Library, Kl. f. 10 is a fifteenth-century astronomical/astrological miscellany made up of many different texts, often thirteenth-century rewritings of Ptolemaic materials about calculations for the cycles of the sun and moon, the times of the year, the astrolabe, and such like topics that were in fashion at that time. It contains both texts and tables.
This field of Greek science is both difficult and understudied, and we must still refer back to eighteenth-century editions, such as Petavius’s Uranologium, pr. Venice 1757, but now ”conveniently” available in digital form (this is not searchable text though, and you must be able to read early print type in Greek). De Andrès made a list of contents of the manuscripts disappeared from the Escorial after the 1671 fire, and it is known that some of those manuscripts have been identified in Sweden. The Linköping codex appears as the descendent of a British Library manuscript, Burney 91-92, just as the Scorialensis was as signalled in the stemma for one of the few modern editions of such types of texts (Régine Leurquin, Théodore Méliténiote, Tribiblos astronomique, Livre I (Amsterdam, 1990), p. 41). Both dating, number of leaves, and contents seem to point in the direction of this identification. Further work is being carried on that might prove this hypothesis even more conclusively.
