A broad opening oval above a compact historical name
A large rounded opening loops above the left of this historical autograph. Smaller connected name forms stretch to the right, with longer pointed descenders interrupting the later band. Compare the opening’s wide empty space with the compact written centre: the initial provides most of the upper height, while the later returns extend the outline below.

Opening, letter body and finish
The opening stays near the height of the body letters. The opening-to-body ratio is 2.00×, while the whole image is 3.45 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 7 enclosed loops and 1 main ink group. The letterforms carry the main horizontal movement; there is no long lower underline detected beneath their band.
Johannes Kepler’s signature in graphology
Traditional graphology associates an enlarged opening loop with public emphasis. The fine compact continuation gives the specimen an economical rhythm, punctuated by more expressive descenders near the later name.
