A large Latin encyclopaedia entitled Liber viginti arcium (The Book on Twenty Arts) was written by Master Paulerinus (Pavel Žídek, Paulus de Praga) in the sixteeth of the 15th century and it is saved as a unique ms. in Cracow, Jagellonian Library, 257. The present contribution contains a first edition of meteorological part of this work (fol. 170rb-172rb), supplemented by Czech translation and commentary. For comparison with this text some parallels are excerpted expecially from Glossarium by Master Claretus de Solencia (c. 1360) and from Nomenclator by Daniel Adam of Veleslavín (published in 1598).
