Cataphract

Those fighting before the standards, around the standards and (otherwise) in the front line were called principes [i.e. the centurions and the other under-officers]. This was the heavy armament, which had helmets, cataphracts, greaves, shields, large swords called spathae, and other smaller swords called semispathia, [...]

Carmine streaks stained their limbs, their tunics and cataphracts; but little of the blood was theirs. They did not move like people with injuries.

And first we must call attention to the fact that two classes of vessels appear to have been employed, distinguished by the name of "Aphract," unfenced, or "Cataphract," fenced, according as the rowers of the upper tier were protected or exposed. Both classes were decked and floored, but the "Aphract" class carried their decks and flooring lower than the "Cataphract," so that in them the rowers of the upper tier were visible above the side of the vessel; [...] [F]rom the time of the invention by the Thasians of this system, all the larger vessels of war used by both Greeks and Romans were Cataphract. In the Cataphract trireme, the space allowed for each oarsman was, according to [B.] Graser, eight square feet per man, and this proportion was observed in the larger vessels up to the octireme.

The ancients either called these ships by their class name (a number plus the -eres root) or by a descriptive term "cataphract" (kataphraktos) which means something like "armored" or "fenced" in the sense of having reinforced decks and sides to protect the oarcrew from missiles and deck-fighting. Because "The Age of Titans" involved galleys whose signature feature was their larger than normal size, and because cataphract galleys could comprise small ships that were protected by extra planking, I frequently employ another term to describe these ships, namely, "big" or "large," from the Greek megala skaphe and its variants megalai nees (big ships) and megista skaphe (biggest ships).
