'Dětmar' (also known as 'Thietmar' or 'Dietmar'; died
2 January 982 in
Prague) was the first
Bishop of Prague. He came from
Saxony, but also spoke
Czech. He was elected as the first bishop in
973, when the diocese was created by
Boleslaus II of Bohemia. The creation of the diocese gave
Bohemia religious independence from the
Empire. Dětmar was rumored to be a wise and pious man, who ordered the building of many churches and the first cathedral. He died in 982.
