Max,
I picked up a box of the Orion Roman sailors last year. The set is terrific. The seated rowers could easily be Greek or Roman. I suppose a few could pass as Viking but I think the Vikings would be more completely dressed. I suppose we could put a horned Helmut on'em and call it done-LOL...
The Dusek 1/72 kits seem to be very nice. Their Trireme looks out of my league but their Greek Bireme seems doable for someone of my limited experience. Add a metal Ram and it would be a perfect model. They sure look to be the most accurate kit replicas of ancient warships so far although Dusek dating these kits to represent the 500BC time frame seems wishful thinking. I would like to try their Bireme but I only have experience with one wooden kit so far and that one is not completed yet. I would buy their kit for a future build but I'm not ready to collect more kits as I cannot afford a divorce.
I like the 1/72 scale so these kits could be displayed with an IMAI (Academy, Ertl, Minicraft) warship so you could have a 50BC-31BC Roman Bireme from an IMAI mold and a 6th century BC Greek Bireme by Dursk. If the Zvezda Kits got some corrections they could be used to fill in the Trireme/Quadrireme /Quinqireme kit voids. The Heller Imperator and Aurora Roman Bireme kits need more extensive fixing I suspect.
The various iterations of the Roman Polyremes is hard to imagine. Hundreds and Hundreds of rowers on vessels so long you'd think they would hog so bad they'd fold up amidships. Too bad we seem to have so many stylized versions in coins and stone, although some of the Stone Carvings seem very believable and compare favorably to the IMAI Roman warship.
I have a few other sources I have been reading. Although only partially complete, they are quite detailed histories of Rome and cover the War at sea quite well.
Greek and Roman naval warfare; a study of strategy, tactics, ... Rodgers, William Ledyard, 1860-1944
And for those who want to try their hand at a plastic Roman warship the following kits may be available:
Academy 1/250 (actually 1/72ish) (IMAI mold 13.3" long)
Academy 1/72 (IMAI mold 13.3" long) Same as above.
Aoshima no scale listed (1/144 to 1/250) (IMAI mold 6 ¾” long)
Aurora 1/80 Roman Bireme 11 1/4" long
B.U.M 1/72 (Barcelona Universal Models) ) (see "Edit" below)
ERTL 1/45 (actually 1/72ish) ( IMAI mold 13.3" long )
ERTL 1/90 ( possibly 1/144 to 1/250) (IMAI mold) 6 ¾" long
Heller 1/75
Heller 1/225 7.4” long
IMAI no scale listed 1/72ish 13.3” long
IMAI no scale listed ( 1/144 to 1/250 suggested) 6 ¾ “ long

Edit: The BUM version I had beieved to be an Aurora copy but box art could depict an IMAI mold kit. I am hoping to see the parts and will update this post accordingly.
Edit: BUM is Aurora copy!
