Dobrzeniecki (in his footnote to the article: Joachim Lelewel jako historyk sztuki w świetle badań Drzwi Płockich i Gnieźnieńskich [Joachim Lelewel as a historian of art in the light of the investigations concerning the Door of Płock and the Door of Gniezno]: BHS, R. 14: 1952 nr 1. <...> S. 10–38) states that it is one of the fi rst mentions in Polish literature about the monument of art that Lelewel calls the Door of Płock in Novgorod. <...> Петербургский исторический журнал № 1 (2015) 114 Th e Romanesque Door of Płock. <...> State of research F.
