What does this glyph (red) mean? Also, what usage was there for it and the other glyph that looks like a colon (blue)?

  • Rx= Rum. Take a look at en.wikipedia.org/wiki/Scribal_abbreviation for the handwriting conventions reenacted in this bit of printing. The wiggle sign over the "a" at the end of the line with your red mark is a missing "m" in "theologiam". The : is (I think) a punctuation mark. Commented Apr 12, 2018 at 3:14

The colon is probably a punctus elevatus which is sometimes written without its tail, i.e. like a colon. It's basically like our modern comma.

  • just found out that not many fonts have this glyph, even premium ones like Garamond Premier Pro are missing it. Such a shame.
