Grabmann was of the opinion that the only logician bearing the name of Simon in the second part of the thirteenth century was Simon of Faversham, since master Simon of Dacia was a grammarian, known especially for his tract Domus gramatice (*).

"The question must be answered now whether the Robertus Anglicus, who is the author of Tractatus quadrantis and the commentary on John de Sacrobosco's De sphera may be also the author of the two redactions of the commentary on Peter of Spain's Summule logicales which we found in the Vatican and Todi manuscripts. Three arguments can be adduced in favour of the identity of our author with the teacher of Montpellier.

"William of Sherwood (born between 1200-10 died between 1266-71) (*) is commonly (*) considered the author of not only a tract De obligationibus but also a short tract called in the only manuscript (Paris, B.

The aim of this paper is to publish the shorter tract from the Paris manuscript and to investigate its attribution to Sherwood.
