On You are not allowed to view links. Register or Login to view., a page from Lawrence J. Schoenberg Collection ms LJS 41 is described as "the woad plant (f. 42), which has a blue root with a human face". The page is also described so:
42: 'Isatoris' (Isatis tinctoria, still in use as a dye plant, woad, the colour indicated by the blue root, though the significance of the face in the root isn't clear)
So, even if the significance of the face is not clear, they have no problem in identifying it as "human".
