Harleian 5218. “Petri Hispani Thesaurus pauperum, Liber medicus cum complexionibus simplicium medicinarum, secundum Gallianum de Sancta Sophya Phisicum.”
I have not been able to consult the following MSS in the Amplonian collection at Erfurt, but mention them as of early date and not listed by Stapper.
Ampion. Octavo 62, early 14th century hand, fols. 124-165, Rubr. “Incipit thesaurus pauperum editus per Iohannem papam.”
Ampion. Quarto 193, end of 13th century to 1362-1364, fols. 2-49. “Incipit liber experimentorum, qui thesaurus pauperum nuncupatur.”
Ampion. Folio 271, 13th-14th century (Schum omits this in the index to his catalogue of the Amplonian collection).
Ampion. Folio 303, fols. 147-63.
Another early copy is contained in a miscellany compiled at Bologna in 1326: Wolfenbüttel 4504, fols. 106-31, Explicit summa medicinalis Magistri Petri Yspani, que dicitur thesaurus pauperum.
A few other MSS of the Thesaurus pauperum are:
Ste. Geneviève 2235, 14th century, “Incipit Summa experimentorum medicinalium magistri Petri Hispani, que dicitur thesaurus pauperum.”
Ste. Geneviève 2237, 18th century, fol. 57, “Incipit pauperum thesaurus summi medicorum monarchae D. Joannis XX (XXI) pontificis maximi cui Petro Hispano ante nomen erat in quo curandorum morborum et theoresim et praxim absolutissime comperies.”
