Arcturius

Hello, I'm new to this Board and a big Roman-History fan. Do you have any source references/links that talk about legions vs. heavy cavalry? This is a big point of curiosity/frustration for me. Many historical texts imply that legions just couldn't stand against heavy barbarian cavalry. The inferiority of heavy infantry on a cavalry-dominated battlefield eventually led the Byzantines to develop Cataphracts as you cite above and so on. But I've seen drawings of legion formations either hurling pila at cavalry breaking their charge or standing with pila extended ready to receive charges. Maybe this was artistic license, but it seems to me a well drilled & equipped legion could withstand any cavalry attack. Any info on this subject would be greatly appreciated. Thanks!
