Abstract
In the present study, the author follows the forms of describing wars and battles in the Czech Chronicle of the Dean of the Prague Chapter Cosmas (ca. 1045 - October 21, 1125), and the aspects on which the author mainly focused. Cosmas describes quite realistically the wars and battles that took place in his time.
In the "descriptions" of all battles, however, he gives much more space to the speeches of warlords, mostly rulers, sometimes on both sides, than to the actual fight. Kosmas puts in commanders not only the usual rhetorical topoi about the reasons for waging war, but also the political views he wants to communicate to contemporaries.
The descriptions of the battles in Cosma's chronicle thus serve, as do other parts of Cosma's narrative, primarily propaganda, which is to affect Cosma's contemporaries.
