His origin and his date of birth are not known. After the death of the Prague bishop Jaromír-Gebehard , Cosmas was elected as his successor in 1091. The investiture by King Conrad took place in Mantua at the end of the year .
Cosmas was accompanied on both dates by the Prague canon and later Bohemian chronicler Cosmas von Prague . The coincidental identity of names, however, led to the fact that the bishop Cosmas and the chronicler Cosmas were confused several times in the sources.
