Thank you all for your encouragements !
It's a pleasure to share the stages of this project with you ... I must also admit that I like the figurines part as much as the one that precedes it, where you have to read as much as possible to get into the subject. !!
I'm starting to get an idea of the units that will be built ... not to mention those that will be reused later.
(not mentionning my comites Alani i could use withour probleme i think :

2x4 Byzantine heavy shield infantry (Orion)
2x4 Roman Late Heavy Infantry (MiniArt)
2x4 late Roman infantry (Italeri... i need more of them, but it seems that the market doesn't propose it anymore
)
3x2 late Roman archers (2 italeri and 1 mini art)

@ Sansovino : the sad battle of Yarmouk !! With Mandzikert, two battles who litterally changed the world of the eastern part of the mediterranean...
Unfortunately except for the orion set, you will find not many possibilities for your byzantine army...
@OwenChpw : conversion is my favourite part !!! i should try greenstuff one day....
@ToneTW ; Giorgio Ravegnani is very helpfull, and as i wrote before there is a lot of his work free online (academica is now my best friend !!)
