An important mathematician, astronomer, Master of Arts (1390) and Doctor of Medicine Kristan of Prachatice (d. 1439) is an author of the first Latin Herbarium of Bohemian origin. The treatise is preserved in its original Latin version (7 manuscripts) as well as in Czech translation (11 copies) and has never been printed. Nevertheless, the Latin and the Czech versions of the Herbarium that were traditionally ascribed to Kristan contain completely different texts. The author of the article points out to two other Latin herbaria of Bohemian origin that were composed in the first half of the 15th century and that show substantial similarities with two of the Czech versions of Kristan's work: (1.) a herbarium preserved in a manuscript in a library of the Royal Canonry of Premonstratensians at Strahov, shelf-mark DG IV 13, fol. 78v-89v, and (2.) a herbarium that constitutes part of a medical volume Confundarium maius written in Erfurt by an Augustinian canon from Roudnice Matous Beran some time before 1431, which is now preserved in the National Library of the Czech Republic in Prague, shelf-mark I F 35, fol. 61r-92v.
