This list covers the Greek states in Bactria and India from Diodotos’ revolt against the Seleucids and founding of an independent Bactrian kingdom until the fall of the last Greek state in India. The revolt was after the adoption of thureophoroi and they appear in Bactrian art, so it is likely that colonist foot were so armed. The Greek cavalry adopted bows in response to horse-archers and elephants. A Bactrian-Greek silver dish shows a cavalryman in Iranian dress with cased bow and using a long lance in both hands, while a Graeco-Indian coin shows a king in Greek armour, but carrying a bow and short spear in a quiver. From 150 BC Bactrian-Greek lancers could be cataphracts. References: Armies of the Macedonian and Punic Wars D. Head, The Armies of Bactria V.P. Nikonorov, Slingshot 217.
