Wargaming maths

HBO's Rome dvd boxed set plus Goldsworthy's "Anthony and Cleopatra" plus Ladybird books equals a wargames project for the dark winter Northern European evenings!
What could be better than pyramids , deserts and the exotic sights,sounds and smells of the Orient to warm one after struggling home through the rain and chill?
Now for some research for illustrations of Cesarian Rome infantry-

A couple of Roman Generals- ideal inspiration for my version of mark Anthony. I am trying to resist depicting him in a lion pulled chariot.
Now Cleopatra and the Egyptian army-

I shall be basing her army and those of her brother on the figure with the spear in the background. So lorica segmentata for the Romans and New Kingdom  for their allies/enemies...
