covered in whole or in part with overlapping metal scales. Eventually, even greaves became less commonly used, although degrees of heavier armour remained, as attested by Xenophon as late as 401 BC. These changes reflected the balancing of mobility with protection, especially as cavalry became more prominent in the Peloponnesian War and the need to combat light troops, which were increasingly used to negate the hoplite's role as the primary force in battle. Yet bronze armour remained in some form until the end of the hoplite era. Some archaeologists have pointed out that bronze armour does not actually provide as much protection from direct blows as more extensive corselet padding, and have suggested its continued use was a matter of status for those who could afford it. In the classical Greek dialect, there is no word for swordsmen; yet hoplites also carried a short sword called the xiphos, used as a secondary weapon if the dory was broken or lost. Samples of the recovered at excavation sites were typically around in length. These swords were double-edged and could therefore be used as a cutting and thrusting weapon. These short swords were often used to stab or cut at the enemy's neck during close combat. Hoplites carried a circular shield called an aspis made from wood and covered in bronze, measuring roughly a metre (3.3 feet) in diameter. It spanned from chin to knee and was very heavy: . This medium-sized shield (fairly large for the period considering the average male height) was made possible partly by its dish-like shape, which allowed it to be supported with the rim on the shoulder. This was quite an important feature of the shield, especially for the hoplites who remained in the latter ranks. While these soldiers continued to help press forward, they did not have the added burden of holding up their shield. But the circular shield was not without its disadvantages. Despite its mobility, protective curve, and double straps the circular shape created gaps in the shield wall at both its top and bottom. (Top gaps were somewhat reduced by the one or two spears jutting out of the gap. In order to minimize the bottom gaps, thick leather curtains were used but only by an unknown percentage of the hoplites, possibly only in the first row since there were disadvantages as well: considerable weight on an already heavy shield and a
