Einleitung

Anotace: The paper summarises available information about the figure of the third bishop of Prague. By the means of comparison with the other known figures of that time it tries to stress the singular features of this person, recognising Thiddag as a very interesting and important individual. Especially in the comparison with his predecessor Adalbert, whose biographers wrote rather a religious and conformal hagiographical work stressing the cliché of a saintly figure, the portray of Thiddag created mostly by his peer and colleague Thietmar of Merseburg presents a rather vivid and trustworthy picture of a diligent bishop with good ties to the empire. Unlike Adalbert he was able to solve his strife with the Bohemian duke and stay somewhat firmly in his office to the end of his days.
