Rosettes and Revelations Pt.1: The Holy City - Koen Gheuens and Cary Rapaport

[Koen G]

That's cool, Searcher! Were you inspired by the Beatus? 
So you use a top-down view, which is logical if you want to include as much information as possible. I think the only area where you compromised may be the foundations - did you place a section of foundation under each gate? Manuscripts either solve the foundation problem by omitting them altogether, or by using a side view and placing tiered foundations under the walls, like a big cake. (As an example, see the one Cary posted above). Showing the foundations in a true top-down view is tricky, unless everything is flattened. The VM solves this by using a top-down view overall but slightly tilting the perspective to show details. 

I need to note that the correspondence between tribes, gemstones and months is quite problematic. I saw many tables and diagrams, and almost all of them differ in this relation.

Do you know where/when these correspondences with months, seasons and elements originated? It makes sense given the significance of four and twelve, but this is not something I have looked into yet. 

I hope you'll feel better soon, fever can really be incapacitating :/
