This paper attempts to reconstruct the now lost aide-memoire notes of Hradec Králové chroniclers, who at the end of the 16th and in the first half of the 17th century used the second dedition of Veleslavín's Historical Calendar (1590) for their notes, recording events of a local nature in particular. In contrast to others which were used by their owners for personal purposes, the Hradec copy of Veleslavín's Calendar came into being in 1590 at the order of the Hradec political representatives and was housed at the Hradec town hall until the 19th century. Today we only learn indirectly of its existence from the testimony of Jan Soukup (1867-1933) and an analysis of the preserved Hradec Králové history by Karel Joseph Biener of Bienenberk (1731-1798) and František de Paula Švenda (1741-1822).
