adds many (probably fanciful) details not found in other sources. According to Hájek, the brothers were dukes who had already owned castles in their homeland before their arrival in the region and dates their arrival to the year 644. Croatian version A similar legend with partly changed names (Čeh, Leh, Meh and sister Vilina), was also registered in folk tales in Croatia in the Kajkavian dialect of Krapina in Zagorje (northern Croatia). However, some believe it isn't of ancient origin but rather it was introduced among commoners by literary people since 16th century. Hajek was the first to mention Krapina as place of origin of Leh meanwhile Čeh ruled over Psar near stream/river Krupa, while Klemens Janicki wrote that Lech emigrated from island Hvar in Dalmatia. Already since 16th century Vinko Pribojević, Faust Vrančić, Mavro Orbini and others from today's Croatia wrote that Čeh and Leh arrived from Croatia and related Czech and Polish language with Croatian, while Juraj Ratkaj was the first to assert that Čeh, Leh, and Meh's origin is in Krapina. Many wrote about it, including Johann Christoph Jordan who personally came to Krapina to hear it told by the local people and mentioned it in De Originibus Slavicis (1745), in 1702 was held a theatre play, in 1848 the three brothers were part of the coat of arms of Varaždin county and the flag was present during the office inauguration of Josip Jelačić, the legend was in addition popularized especially by Ljudevit Gaj, while Stjepan Ortner published the legend in full form in 1899. The legend was one of the reasons Croatian language was chosen in 17th century as the common Slavic language for Catholic books for all Slavic nations. Debate In the Bohemian chronicles, Čech appears on his own or only with Lech. Čech is first mentioned in Latin as Bohemus in the Cosmas' chronicle of 1125. The earliest Polish mention of Lech, Čech, and Rus' is found in the Chronicle of Greater Poland written at the end of the 13th or the beginning of the 14th century. The legend suggests a common ancestry of the Poles, Czechs and the Rus', and illustrates the fact that as early as the 13th century at least three different Slavic peoples were aware of being ethnically and linguistically interrelated. The legends also agree on the location of the homeland of the Early Slavic peoples in Eastern Europe. This
