The half-popular compositions traditionally referred to as broadside ballads are a specific type of source. Some of them reflect Biblical, legendary and historical events in Egypt and the Near East. Although the factual importance of such ballads in not great, they have some informative value, because their texts mirror the attitudes and opinions of the lower social classes, in this case clearly influenced by the antithesis of Christianity and Islam, or also Judaism. They show that the authors of broadside ballads kept alive deep-rooted stereotypes, mainly the stereotype of Turks as pagans and tyrants. and Michal Klacek.
The catastrophic floods in the Czech lands in July 1997 and August 2002 showed that historical flood memory had been lost. The little used sources to recover it include early printed books. This article brings a selection of several exceptional flood cases captured by printed documents from the 16th-18th centuries. Extant early printed books and the information that they contain (verified from other sources where possible) suitably complement and extend the potential of historical hydrology and meteorology for the study and documentation of early floods that occurred before the beginning of instrumental observations and measurements. and Jan Munzar, Stanislav Ondráček, Lubor Kysučan.
