VMs f75r - Nymph Holding Spurtle

[Barbrey]

That's the VMs artist's modus operandi, doing things in odd ways - intentionally - visual trickery, ambiguity, duality, heraldic canting, code shifting and so on.

You and I agree on this, R. Sale, but here’s the thing, I wonder if we shouldn’t necessarily be looking at books of heraldry, or alchemy, or herbals or religious iconography, but whether there is any medieval text or tradition of the time period incorporating these types of textual/visual obfuscation (and I include negation in this) on such a scale. I don’t even know how I would search for this - is there a name for this type of writing?
