A Roman altar is displayed in the porch of Haddon Hall, near Bakewell in Derbyshire (RIB 278). It is reported to have been found prior to 1695 (its first known mention in Camden’s Britannia) by the river in the grounds of the hall.
The altar is dedicated to Mars Braciaca by Q. Sittius Caecilianus, prefect of the First Aquitanian cohort.
The same unit is attested at Brough on Noe (Navio; near Castleton, Derbyshire) c. AD 158, during the reign of Antoninus Pius and the governorship of Iulius Verus (RIB 283). Prior to this (probably during the governorship of Sextus Iulius Severus, c. 130) the unit seems to have been located at Carrawburgh on the line of Hadrian’s Wall (RIB 1550).
Anthony Birley has suggested that the Sittii family could be from the area of Cirta in Africa, and that Caecilianus “may also be regarded as a Numidian”.
