On the Roman Centurion Galea helmets, did the direction of the plume signify anything?
Some are vertical, others are horizontal (transversal), and was there a symbolic difference between the two, or was it purely aesthetic?
Centurions, tribunes, and above, wore a modified galea with a plume.
But only centurions wore the transversal crest (aptly called Crista transversa). Higher commanders wore vertical plumes on their helmets. Enlisted men wore the simple ones, though it is debated whether they wore them in combat or only for ceremonial purposes.
The reason for this is that the transversal crest makes the officer easier to spot on the battlefield. Whether that was the actual reason or just a later explanation is unclear.
At the beginning of each battle, a centurion's position was predetermined, and from that point on it was his duty to be observed by his men to maintain awareness of his location and follow his commands. Also, battles rarely became completely chaotic due to Roman tactics, discipline, and general superiority. When soldiers were positioned in infantry squares, the transversal crest must have been extremely visible.
Since Caesar was a senator, he was entitled to wear the galea with a purple plume.
However, Caesar’s rank was higher than this; he was also consul, proconsul, and governor.
Lucius Vorenus, one of the centurions mentioned in Caesar’s writings, being a centurion, was entitled to a transversal plume on his helmet.
Readers should note, the Roman helmets were vastly redesigned after this period.
What did the Roman Army use to keep their weapons from rusting?
Oils, greases, and a hefty dose of fear. Every legionary was expected to show up with his gear in perfect condition. If he did not, his decanus should have addressed it.
If the decanus failed to catch this, it should have been caught by the tesserarius.
If the tesserarius did not notice the negligence, it was the task of the optio.
One of the centurions, as shown in illustrations, also carries a stick. This is not symbolic but a beating stick. He is authorized to punish everyone under his command: the offending legionary, his comrades, the decanus, the tesserarius, and the optio. Yes, centurions had the duty to physically discipline anyone who disobeyed.
This man had almost unlimited authority to punish his century, and all sources indicate they exercised it fully.
Centurions were encouraged to apply the harshest punishments to ensure issues like rust never occurred. According to all recorded sources, they took this power seriously and enforced it with vigor.
Besides beatings, soldiers could be forced to sleep outside the camp, denied regular rations, assigned extra duties, or even demoted.
Please note, these officers were not merely administrators. These plebeian men were survivors of years of combat who fought their way up the ranks. They fought on the front lines with their men, and tolerating rust on a legionary’s gear was inconceivable.
Legionaries often complained about the cruelty of their centurions. However, these complaints seem to have been ignored by commanders since there is no record of a centurion punished for being too harsh on his century.
All that said, this strict discipline was tolerated for a reason: these men led from the front and had fearsome casualty rates. They were viewed as the toughest and most feared soldiers. Caesar recounts a tale in Book 1, Chapter 25 of the Gallic Wars:
"All the centurions of the fourth cohort were slain, and the standard-bearer killed, the standard itself lost, almost all the centurions of the other cohorts either wounded or slain, and among them the chief centurion of the legion P. Sextius Baculus, a very valiant man, who was so exhausted by many and severe wounds that he could barely support himself; he perceived that the rest were slackening their efforts, and that some, deserted by those in the rear, were retreating from the battle; the enemy, though advancing from lower ground, were pressing hard on both flanks. Having snatched a shield from one of the soldiers in the rear (for he himself had come without one), he advanced to the front of the line, addressed the centurions by name, encouraged the rest of the soldiers, and ordered them to carry forward the standards."
This account shows how crucial centurions were for the Roman legions.
