Morten Mogensen was born at Ribe in Jutland  probably in the late 1240s or early 1250s.

From the 1290s, he held a Prebendary as Canon of the Ribe Cathedral in the Ribe diocese  as well as Provost of Schleswig and Canon of Lund. In Schleswig, Mogensen established a vicarage in the parish of Sywertmanrip. Mogensen was  mentioned in 1288 as royal chancellor of Danish King Eric VI Menved  (reign 1286 –1319). In the dispute between Jens Grand, Archbishop of Lund, and King Eric VI Menved,  Mogensen arranged  a royal rapprochement to Pope Boniface VIII, which in 1302 resulting in a settlement of the dispute. In 1302 he gave a donation to the chapter of Notre Dame in Paris. He founded an altar for the cathedral in Roskilde in 1303. Mogensen died during 1304 in Paris and was buried at Notre Dame. Name
The rendering of his name, Morten Mogensen, into Medieval Latin as Martinus de Dacia stems from the fact that, during the Middle Ages, the toponym Dania  meaning Denmark, was occasionally confused with the historic region of Dacia in the Balkans. Works
