 Modi significandi had a considerable diffusion, evidenced by six extant copies from the thirteenth, five from the fourteenth, and two from the fifteenth century. Strong influence from Boethius has been detected in the anonymous question commentary on Priscian Minor known as Innata est nobis, where he is referred to as “a famous man” (Pinborg 1967: 93–4). The Summa grammatica of John of Dacia (1280), while more dependent on Martin of Dacia’s Modi significandi, also owes a considerable debt to Boethius (Pinborg 1967: 87). According to Pinborg (1967: 91–2), Boethius further left his mark on Michael of Marbais’ Summa de modis significandi, but this has been called in doubt (Kelly 1995: XLV).
