The angustus clavus was a narrow, the latus clavus a broad, purple upright stripe (possibly two stripes) stitched to or woven into the Roman tunic (see dress). The former indicated equestrian, the latter senatorial rank. Under the emperors the latus clavus was worn before admission to the senate, on the assumption of the toga virilis, by sons of senators as a right. The latus clavus could also be granted by emperors to men of non‐senatorial origin; the award of the latus clavus gave such men the right to stand for senatorial office. Military tribunes (tribuni militum) in the legions were distinguished as tribuni angusticlavii or tribuni laticlavii according to whether they were pursuing an equestrian or senatorial career.
