The flower in the corner...

On page f17r, there's a faint flower (or seed-pod) drawn in the top right corner, coloured in by a few remnants of blue paint. Reminds me of the decorative feature in the balneological section (in much the same place on the page on f84v). That seems to tie the two together... don't know what it means, though.

Perhaps there are lots more faded drawings on the VMs - sounds like a job for a non-specific UV scan to me...
