Use of the spear in two hands on horseback

[Sean Manning]

Have a look in my new book "The Gods of Battle" where this topic is discussed extensively. You can see two-handed holds in some Macedonian tomb paintings and the Alexander mosaic and in the Kazanluk tomb. I argue that a lance had a spear-butt/counterweight on the rear end as well as being (in later versions) tapered to allow for the two-handed hold and a longer reach. http://www.pen-and-sword.co.uk/?product_id=2852

Until I can see your book, do you remember who in the Alexander mosaic (link) holds a spear two-handed? Alexander holds his xyston one-handed, so does the man in the Boeotian helmet behind him, the standing Persian holds his palton one-handed, and we can't tell how the Persians in the background carry their long lances.
