Variant: scroll with dots

·    Subvariants (3):

o A. Full: head with “leaf” on the left (usually just a boulder outline instead of a leaf outline)

§ Left: boulder/leaf with bold scroll inside – the scroll has two or three dots on the outer edge, optionally (but very often) cross hatched.

§ Right: head, which can be “turtle”, “bird” or “skull”-like

o B. Reduced: left part of full form.

o C. human head: a generic

§ This is simply the “animated form” of this glyph – a generic head with the defining characteristic of this glyph (the scroll with dots = reduced subvariant) infixed.

§ Only Bonn has recognized this form (0021hh).

·    Tokovinine explains in a lecture/lesson (lost reference) that in the early stages of the Classic Maya script, bu and mu were not distinguished, probably because they were borrowed from a language which didn’t distinguish between /b/ and /m/. But as this distinction is important in Classic Maya, they gradually developed two different forms:

o bu with (cross hatched) dots on the scroll.

o mu without dots on the scroll.
