The unit is great as usual though Spartans are not my cup of tea. But it looks like I missed good news?
I fully support the request for a Winged Hussar, and the one from 1612 looks great, just don't make him so beaten up
The old ones are inaccurate or not Civ3-like at all, e.g. Piernik's. I tried to make one myself as well but couldn't find/make proper wings either.
There's a number of Russian and Polish ones released with English subtitles. Apart from 1612, the ones I've seen I can recommend: Andrei Rublev, Alexander Nevsky, The Deluge, Colonel Wolodyjowski, With Fire and Sword. The first 2 are Russian set in the 13-14c Russia, the other 3 are Polish set in 17c Polish-Lithuanian Commonwealth, incl. later Russia/Ukraine.
