Two dark groups with a broad surname C
A dark angular first group leads into a much larger rounded surname opening. Small connected forms continue toward a long low right-hand tail, with a deeper return near the middle. Compare the open C space with the denser smaller letters: the surname’s beginning is a clear landmark within the otherwise compact historical name.

Opening, letter body and finish
The opening stays near the height of the body letters. The opening-to-body ratio is 1.48×, while the whole image is 3.17 times as wide as it is tall. The rightmost ink finishes above the writing line; look at this ending separately from the slant of the letters themselves.
Loops and the lower flourish
The sample contains 1 enclosed loop and 4 main ink groups. The letterforms carry the main horizontal movement; there is no long lower underline detected beneath their band.
Nicolaus Copernicus’s signature in graphology
