4th-century shoulder bag?

[Sebastianus]

The only other bag I can think of at the moment is this one from Barhill so of Antonine date mid-late 2nd century its very fragmentary but also very simple the method of "herringbone" lacing is pretty common, the form is a folded piece of thin leather approx 45x30cm (so 45x60 before its folded), a medium sized goatskin would supply all the material necesary, the offcuts would be used to make the lacing, calf could also be used.

Thanks for the tip - I have a veg-tanned goatskin that is about the right size.  Looks like the proposed "handle" would have been to hang from a furca?  I'll try to track down the report this comes from, but maybe a braided shoulder strap would work.  I imagine for the seams, it's essentially worked like a crocheted chain through the lacing holes at the sides of the bag?
