SINONOMA BARTHOLOMEI. 



THE accompanying Glossary is taken from a manuscript of the 

 fourteenth century in the Library of Pembroke College, Oxford, 

 which has been already described by Mr. Riley in the Sixth Report 

 of the Royal Commission on Historical MSS.^ (Part I, 1877, p. 550). 

 The work consists of a medical treatise on diseases and remedies 

 in fifteen parts, with a glossary and index, composed by John 

 Mirfeld or Marfelde, and is entitled ^ the ' Breviarium Bartholomei,' 

 in honour of St. Bartholomew's in London, of which monastery the 

 author was an inmate^. 



Prefixed to the main work is a Calendar for the year 1387, 

 and a series of calculations for a perpetual Calendar for the meri- 

 dian of Oxford, by Magister Walter de Elvesden, together with a 

 number of astronomical tables. 



John Mirfeld or Marfelde is mentioned by Leland (' Commentarii 

 de Scriptoribus Britannicis,' c. 582) in the following passage, which is 

 repeated by Bale, Pits, and Tanner : 



'Joannes Marifeldus homo ad philosophise et rei medicae cognitionera 

 reconditam illam compositus, eo eruditionis pervenit ut a civibus Londinensibus, 

 per eum nuUo non morborum genere curatis, immortalem famam acceperit. 

 Scripsit de arte medendi vel justum volumen quod et Praxin, Gilberti Anglici 

 medici clarissimi industriam secutus, vocavit : quo opere, ut Gilberto interiori 

 causarum cognitione cessit, ita in praxi eundem longo praecessit intervallo. 

 Multa mihi de hoc Marifeldo narravit Bertholetus medicus, adfirmans eum 

 sedes propter Xenodochium Berptolomeanum Londini incoluisse.' 



' The MS. of the Breviarium BartholomcEi in the Harleian CoUection [No. 3], mentioned 

 by Mr. Riley, does not contain the Sinonoma, 



* ' Incipit liber qui intitulatur Breviarium Bartholomei compositus per venerabilem virum 

 Johannem Mirfeld commorantem in monasterio Sti. Bartholomei, Londofi, a quo liber iste 

 denominatur.' 



^ There are in the Calendarium Inqiiidtionum post Mortem, iii. 150, 159, two occasions on 

 which John Mirfeld and others represent the Convent of St. Bartholomew. These bear date 

 i^th and i6th Rich. H, or 1392-1393.
