The Academy of Sciences Library has purchased a so far unknown illumination with Bohuslav Hasištejnský’s epitaph of Jan of Vartenberk († 1508) from the Swiss antiquarian bookshop Dr. Jörn Günther Rare Books AG. The illumination, Hasištejnský’s epitaph (with the meaning adjusted to the context) and the commemorative inscription present the figure of the Litoměřice Canon Jan of Vartenberk, who was sent to Pavia by Charles IV in 1355 to fetch the relics of St Vitus. We suppose that this illumination was probably made for Jan Jiří of Vartenberk as a component of a larger whole around 1615.
