Lars 573

Well I am not quite sure I follow you, are advocating the spears being the same length or changing?

In any case your hoplite pictures have spears that are too short for either 500 B.C. or 300 B.C.
A hoplite spear should be about one and half times (or perhaps a bit more) the hoplites height, thus the typical 8-9 ft estimate.
The length pictured would be more appropriate for the Persians.
