What unit from the Roman Army consisting of centuries enjoyed more prestige than the Roman navy?
Roman legion A Roman legion (from Latin "legio" "military levy, conscription", from "legere" "to choose") was the largest unit of the Roman army, evolving from 3000 men in early times to over 5200 men in imperial times, consisting of "centuries" as the basic units. Until the middle of the first century, 10 cohorts (about 5,000 men) made up a Roman Legion. This was later changed to nine cohorts of standard size (with 6 centuries at 80 men each) and one cohort, the first cohort, of double strength (5 double-strength centuries with 160 men each).
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.
