Ist Cohort Size

[Forty-One]

Ian Richmond's plan of Inchtuthil (c. 84 to 86 AD) shows very convincingly that one of the cohorts there had five centuries with double the space allocated to them, and five small courtyard houses (presumably for the centurions). According to Keppie's book about the "Making of the Roman army" epigraphic evidence from this period, and later, only attests to the existence of five centurion posts in the first cohort.
