"Ondřej Schmidt's biography is impressively successful. Painstakingly documented, methodically structured, skilfully written, and competently translated, Schmidt's John of Moravia makes for a pleasant and instructive reading for a medievalist". Marian Coman, in The Medieval Review, June 2021.

"The book is a significant contribution about a member of the House of Luxembourg’s final generation by a young author. In general, I regard the book as seminal for two reasons: first, it puts a definitive end to ambiguities about this member of the Luxembourg lineage and clearly identifies John of Moravia in relation to John Sobeslav; second, it relates a thus far little known story about his life in the Patriarchate of Aquileia". [...] The book is an excellent biography of a personage who left a trace not only in Czech but also in Italian lore. In view of this, it can be recommended to all those interested in the House of Luxembourg, the political history of unsettled central Europe, and even the Apennine Peninsula in the second half of the fourteenth century". Tomás Velicka, in Speculum, 96/2 (April 2021).
