These are among the largest ancient ships that Langton makes. For Tékumel, they will fill the role of the zírunel, the largest of the common classes of warships. I believe that they are larger warships plying the oceans of Tékumel, but they are rare and I will not worry about them, for now...
The next step down in size, these are slated to represent the qél for my Tékumeli navies. I was pleasantly surprised to see that the relatives sizes of these miniatures are very close. This will allow a lot of variety, not only for different navies but also within a particular empire's navy (Langton has other miniatures of this size that I have yet to purchase).
These three miniatures are markedly more narrow than the previous four, as well as being slightly shorter. For Tékumel, I think these will work as the srügánta, although the hemiolia is a bit smaller than the other two and might be better as a séscha. Out of these, the liburnian is especially appealing with the stern platform.
Overall, I am quite pleased with the appearance of these miniatures. There is still work to do, as the representation of a séscha is not fully set yet, and there are a couple of trireme variants I would like to look at before setting it all in stone (heh) for the building of some flotillas.
