Thanks a lot. Do you know, what the Text markup would be to get the
neomensural signs printed centered on the staves? I couldn't find that
in the docs.

As far as I recall, the translation from the semibrevis sign in old
scores to our modern note values is more or less arbitrary (being a
factor of 1, 2 or 4). But the meaning of the neomensural "prolatione
perfecta" time signature glyph invariantly means (by definition) to
contain 3 semibrevis.

As the lilypond developers decided to identify the semibrevis sign
with a whole note (which is the way most modern scientific editions do
it as the visual appearance has a closer resemblance to the original
score), the prolatione perfecta invariantly means 3/1.
