A Book of prophecies or Chrismologion (also Chresmologion; χρησμολόγιον; latinized Chrismologium) is a genre of literature of the Renaissance and the Early Modern period which collects prophecies or methods of divination.
The Chrismologion of Paisios Ligarides (c. 1652) was a collection of prophecies to the effect that the Russian Christians will defeat the Ottomans and liberate Constantinople are dedicated to the Tsar. Similarly, a Russian translation of a 1673 Greek Chrismologion was dedicated to the Tsar by Nikolai Spathari.
Bohemian astronomer Martin Horký published a series of almanachs entitled Chrysmologium Physico-Astromanticum during the years 1639–1645 containing both astronomical calculations and astrological predictions for the year in question.
