Legatus
A legatus was a delegated representative in Roman government and warfare. According to period and assignment, he could be a senatorial envoy, a commander’s subordinate, a legionary commander or an imperial provincial governor. The word did not denote one unchanging military rank.
In the Principate, a legatus legionis normally commanded a legion under the provincial governor. A legatus Augusti pro praetore governed an imperial province and might command several legions. Provincial arrangements and powers changed; not every governor bore this title.

Position in the command structure
Alongside the legate in a Principate legion served a senatorial tribunus laticlavius, five equestrian tribuni angusticlavii and a camp prefect, often a former primus pilus. Their responsibilities differed: the senatorial appointment formed part of a public career, while the camp prefect drew on long military experience and supervised the camp and material organisation.
This arrangement cannot be applied without exceptions to every force and province. Appointments, the number of subordinate units and the combination of military command with provincial government changed. Comparing a legate to a modern general is approximate and does not prove that senior commanders never personally took part in combat.

Honorific portraits of senior officeholders often use a muscled cuirass, cloak and decorated objects as a language of authority. The statue of Marcus Holconius Rufus from Pompeii is one example. Inscriptions identify him as a local magistrate, military tribune and priest of Augustus; they do not establish that he was a legionary legate.
The duumvirate belonged to municipal government, while patronus coloniae meant patron of the colony, not its highest municipal military commander. The statue is useful for studying honorific military imagery but is not a precise guide to a legate’s field uniform.

- Lorica musculata: an anatomical cuirass, often bearing symbolic scenes.
- Garments and hanging strips beneath the cuirass: comparison with a subarmalis does not reveal the material and construction of every layer.
- A cincture around the cuirass: part of a commanding image, not independent proof of a legionary legate’s appointment.
- Paludamentum and tunic.
- Parazonium: a weapon represented in high-status imagery.
- Calcei: closed footwear; a sculptural type should not be prescribed for every field commander.
A helmet, arms and armour for reconstruction should be selected from dated evidence rather than assembled from the richest statues of different centuries.
