Herbal ms Florence 106 (1400 ca)

[oshfdk]

Structurally, it behaves more like an instrument or reference aid: diagrams dominate, text never explains anything, and the same tightly constrained writing system is reused across very different kinds of pages. That’s a strange design if the goal were teaching or description, but it’s exactly what you’d expect if the manuscript was meant to be used by someone who already knew the system.

This is not how I see it, I think proper diagrams are relatively rare, if you don't count the plant images. And there are plenty of text-only pages with no drawings at all. I'm not sure I understand "text never explains anything" part, how can we know this without reading the text?
