Friday! This week, we're going to look at the difficult logistics of large armies on the move in a pre-modern society, as well as the impossible logistics of feeding a large city at long distance overland. All this, plus Game of Thrones nitpicking!https://acoup.blog/2019/10/04/collections-the-preposterous-logistics-of-the-loot-train-battle-game-of-thrones-s7e4/ …

Is there a general rule for how far food can be shipped by sea in the premodern world before it’s too far? Could they have shipped it from Highgarden to Kings Landing?

Obviously it varies a fair bit. One rule of thumb we lean on in Roman history is that the Price Edict of Diocletian (an attempt at state-run price fixing) was that travel costs by road:river:sea were 20:4:1 (sea travel is roughly twenty times cheaper than road).

For the Roman world, one of the longest major bulk-good shipment pattern I can think of is grain from Egypt to Rome - that's massive bulk goods moving c. 1600 miles (once you account for coastlines and wind). So you could sea-transport bulk goods a long way.

That said, Westeros' geography is just...very hostile to long distance trade. I'm not the first person to point this out - Westeros should be much more fractured - econ. polit. and culturally - than it is.

I should note in talking about longest major bulk goods route, I'm leaning heavily on 'major' - amphora from *everywhere* in the Roman world show up in all kinds of crazy places, probably after making multiple hops to get there.

But that trade network is very reliant on favorable waterways - The Mediterranean, and major rivers punching inland from it create a vast common for trade in the Roman world that Westeros just doesn't have - no inland sea and all of the rivers point away from trade partners.
