This will be my all time super-favorite mod, I guarantee that. But there seems to be a confusion regarding the offensive and defensive gear, so I'll contribute some data (I am a military history professional and my area of specialization lies precisely in ancient greece)Q
- swords
xiphos - the standard greek sword. Straight, double edged, about 55-70 cms long. The Lakonian (spartan) version of the xiphos is much shorter (like 40-50 cm. long). A longer xiphos was used in the 4th century BC (up to 80 cm. long). The Lakonian sword was sometimes referred to as "xiphidion"
kopis - the curved, mostly used by cavalry (and the later macedonian footmen) falchion-like sword. Single-edged, about 60 to 70 cms long
machera - refers either to a straight, xiphos-like sword, or (more commonly) to a very large knife (like 40-45 cm in length).
Parazonion (or parazoonion) - dagger
- Spears
Dory - the standard hoplite spear. About 2 to 2.5 meters long, with a buttspike and a leaf-shaped tip.
Sarissa - the phalangite pike. About 5 to 6.4 m. long, huge tip, big buttspike
Xyston - the typical cavalry spear, ranging from 2.5 to 3 m. long, complete with buttspike
hippiki (cavalry) sarissa - the cavalry version of the sarissa, same as above but up to 4 m. long
Palto - the typical dual role (javelin/spear) weapon of the cavalry of the Peloponesian war era. About 1.5 m. long, could be either thrown or used as a spear.
Grosphos - the typical javelin of the period. Up to 1.5 meters (usually shorter). Also called "Hyssos" and sometimes "Aechme" (the latter is not very popular, and most of times would refer to just the tip)
Kondos (or Kontos) - this comes into use in the later hellenistic period and would designate a lance, although it was used also for long (but shorter than sarissas) spears
Doration - light, short (less than 1.80 in length and with a small tip) spear
- Cuirasses
Thorax - the typical metallic cuirass, made of bronze
Linothorax - padded linen thorax, very popular from the 370s BC and on. Came also in luxurious varieties (with plenty of metallic addons for greater protection)
Spolas - hardened or padded leather, extremely popular in all times, was the standard defensive gear for the light troops
- Helmets
Pilos (also refered to as "Lakonikos pilos") - a bronze or iron helmet, shaped like a felt hat. The same name applies to a felt hat
(the rest of the names are modern, because the ancients didn't seem to have had particular designations)
Korinthian helmet - the typical hoplite badass helmet that covers fully the face (save eyes and mouth)
Illyrian helmet - same shape as Korinthian, but does have a large opening in front and leaves the face exposed
Boeotian helmet - a very different helmet, the one used by Alexander's companions
Phrygian helmet (think of Alexander's foot companions)
Causia - the typical hat of the Macedonian greeks (I guess you are including hats as well)
- Shields
"Hoplon" (or aspis) - the typical hoplite shield. 90 cm to 1.10 m. wide, wood coated with three or more layers of bronze, or even (in some occassions) fully of bronze (great protection the latter, but VERY heavy)
Pelte - the light, crescent shaped shield from Thrace, later it meant all the light shields (sometimes even the shield of the Macedonian pezheteroi was called "pelte", besides aspis)
Thureos - Oval shaped shield, modeled after the Galatic designs (was used in the 3rd century BC and on in Greece)
- Other
gastraphetes - a primitive form of the crossbow (or, more likely, the arbalest). Was held and fired from the belly level ("gastros" is the belly).
romphaea - the dacian/thracian falx, in it's greek incarnation.
Toxon - the bow
toxon persiko - the Persian bow, significantly better than the early (5th century) Greek designs
toxon skythiko - the skythian bow, a powerful composite bow, the weapon of choice for the famous Cretan Archers. The Cretans came up with a variant of the skythian bow, the "toxon kritiko", that was even more effective.
This is from the top of my head. If you need any further info, just tell me. Good luck with this project, it's great.
