So now they're in Egypt

[ReneZ]

Any ideas or suggestions?

The problem with looking at coins has already been pointed out a couple of times....

I'm sorry but the idea of comparing the pharma containers with the lighthouse of Alexandria seems like a classical case of projecting one's ideas onto the illustrations in the MS.
Now why do I say that?

Whatever the pharma containers represent, they all appear in the same context in the MS, so there can be no doubt they all have the same meaning. This discussion came up already years ago, when some of them were pointed out to look remarkably like early microscopes, but others clearly don't. Similarly, purely from the geometry, some of them look like Alfonso's cannons, but others don't.
In addition, there isn't a great reason to expect microscopes or cannons in this place in the MS.
(This is a very brief version of an executive summary of two longer stories of course).

Now *IF* one container is supposed to represent a tower, then shouldn't all be representing towers?
What's more, in the middle ages, the whole of (what is now) Italy was filled with towers from north to south.

So why pick Alexandria?

On top of that, a tower is as much out of place here as a cannon.
