Leather and shoes, further updates

I've been in a lengthy and very informative discussion about leathers over at RAT, and it seems that grained leather may be on the table again.  This is not inconsistent, since what I've read from brain-tanners is only that it's not easy to get the same softness from a hide without scraping the grain off; they never said it was impossible.  Member Ivor (Crispianus) brought to my attention two things I found surprising:  a modern repro of an Iron Age shoe, tanned with fish oil with the outer grain intact, and a detail from a piece of Hellenistic statuary showing a pair of Iranian shoes from the side.

It is a scan from Skulpter des Hellenismus.  It shows that the ankle shoe in this period was made not from a one-piece upper (a la the Plains moccasins and Hedeby shoes I'd been using as a model), but from a separate vamp and quarter.  This allows the quarter to rise as high or low as you like, whereas a one-piece upper has to have extensions sewn on if more than a certain height is desired.

(It further means that the Minnetonka moccasin boots are less inaccurate than I thought, and with a little modification, are actually the only off-the-shelf shoes I've seen that are anything like acceptable.  I managed to pull the heels off mine recently, but since they only appear to be available in soft sole now, you could just glue or tunnel-stitch your own leather/rawhide soles without having to potentially rip the bottoms up.)

For comparison, I went searching for high-res pictures of the Alexander Sarcophagus, which is one of the best sources for Persian clothing at the transition of the Achaemenid and Hellenistic periods.  In the restored-color versions by Vinzenze Brinkmann and Ulrike Koch-Brinkmann, the straps appear to encircle the ankle like those on Median shoes on the reliefs at Persepolis, but without the "branches" going down the sides.  However, there is an extreme closeup over at Wikipedia which appears to show a faint vertical ridge on the central figure's shoe.

With regards to the Persepolis reliefs, Ivor pointed out that the vertical branches could easily be interpreted as strips of reinforcement running down the front edges of the quarter.  The ankle strap itself - as he demonstrated by sewing an example - was probably just stitched to the top edge of the quarter rather than running through slits (as per moccasins).

The later example above is slightly modified, with the lace running through a single pair of eyelets, essentially making it a very simple chukka.  In this configuration, the eyelets are under much more stress than in the first, since they are pulled forward to hold the top around the ankle, whereas when running the thong around the ankle (either through slits or sewing it on) doesn't pull the shoe leather, but merely squeezes it against the ankle, like a drawstring.  Therefore, the later configuration would do well to have a reinforced eyelet.
