The Ivan Potrč Public Library contributed to the Digital Library the work Gratae posteritati from 1560; it is one of seven autobiographical works of eminent diplomat Žiga Herberstein, the most famous member of the Herberstein family. Compared with the first edition of this work in 1558, this one is more extensive, attractive and more richly illustrated. Hand-coloured prints with images of nine rulers of the time, the Herberstein coat-of-arms and six portraits of Žiga Herberstein give a special charm to the book. The copy from Ptuj is one of the few preserved coloured copies in the world; it is especially valuable because it comes from the library of the Counts of Herberstein, who were the owners of the Ptuj castle from 1873 to 1945. The digital version of the GRATAE POSTERITATI is also available on the Digital Library of Slovenia portal.
