Representação de um cavaleiro catafractário, à maneira da era sassânida. Os catafractários (grego: κατάφρακτος, kataphractos ) eram uma unidade de cavalaria pesada utilizada por povos antigos (sármatas, partos, armênios e, posteriormente, romanos e bizantinos). A armadura utilizada por esta cavalaria se chamava catafracta. [ 1 ] Referências ↑ Bivar, A. D. H.
