[1] The work of the first anonymous continuator covers the years 1125/1126–1141, being essentially annals of the reign of Soběslav I.
He ended with the death of Soběslav and the accession of Vladislav II in 1141, but an entry covering the civil war of 1142 and a miracle wrought by Saint Ludmila was added to the text in 1151 or 1152 by someone working in Saint George's Church in Prague.
[2][1][3] Narrative sections include accounts of Frederick Barbarossa's second Italian campaign in 1159–1160; Otakar II's rebellion in 1248–1249, drawn from a Venceslai I regis historia (History of Václav I); Otakar II's war against Hungary in 1260; Otakar II's war for the German throne, culminating in his death at the Battle on the Marchfeld in 1278; and the rule of Otto V of Brandenburg that followed, including a major famine in 1282.
[1] The compilation ends with the Epilogus interpolatoris, an account of the legendary founding of Czechia and a list of Czech rulers down to Václav II.
[1] Vincent of Prague, whose chronicle covers the years 1140–1167 of the reign of Vladislav II, may also be regarded as a continuator of Cosmas.
[3] In the 1170s, an anonymous monk of Sázava combined a history of his monastery from its foundation—De exordio Zazavensis monasterii[1]—with a continuation of Cosmas down to 1162.
