What unit from the Roman Army consisting of centuries enjoyed more prestige than the Roman navy?
Roman navy The Roman navy (Latin: "Classis" , lit. "fleet") comprised the naval forces of the Ancient Roman state. The navy was instrumental in the Roman conquest of the Mediterranean basin, but it never enjoyed the prestige of the Roman legions. Throughout their history, the Romans remained a primarily land-based people and relied partially on their more nautically inclined subjects, such as the Greeks and the Egyptians, to build their ships. Because of that, the navy was never completely embraced by the Roman state, and deemed somewhat "un-Roman".
Bryennios Bryennios or Bryennius (Greek: Βρυέννιος ), feminine form Bryennissa (Βρυέννισσα), was the name of a noble Byzantine family which rose to prominence in the 11th and 12th centuries, mostly as military commanders. The etymology of the name is uncertain. The first members of the family appear in the 9th century, with the "strategos" Theoktistos Bryennios. None are known for the 10th, but they reappear in the latter half of the 11th century, when they rose to high military commands and became associated with the Komnenian dynasty. Members of the family retained high positions through the 12th century, and are documented up to the 15th century.
