“Jacob Campo Weyerman and his Collection of Artists' Biographies is a great book. Not cheap, but the first 141 pages, Part One, will serve as a new benchmark in Weyerman Studies.”Peter Altena, in JCW 43.2 (Mededelingen van de Stichting Jacob Campo Weyerman)"The fact remains that, whatever [Weyerman's] motivations, he demonstrated (and de Vries amply acknowledges it) that he had an art critic training, that he mastered a technical vocabulary that deserves to be studied precisely because it is specific to a reality and an era and, in short, that he was a man fully immersed in his time. Probably these findings (and the many references to the situation of the art market in the Netherlands [...] would today satisfy more those who deal with social history of art, rather than history of art in the strict sense; however, they allow us to reconsider the importance of a work that, in Schlosser's time, seemed inevitably destined for oblivion and ignominy."Giovanni Mazzaferro, in: Letteratura artistica: Cross-cultural Studies in Art History Sources, August 2020
