Leonh Euler with a small abbreviation dot

The first group writes Leonh in fine connected forms. A small dot separates it from a broader looped Euler opening and a low readable surname band. Compare that word division with the joined strokes within each region: the specimen presents a compact first-name abbreviation and a more spacious beginning to its second word.

Leonhard Euler signature analysis

Leonhard Euler’s signature sample has a forward slant at the edge of the measured range, a near-level baseline and 5 enclosed loops. Use the layers to follow the writing line, letter band, slant and enclosed loops.

Opening, letter body and finish

The opening stays near the height of the body letters. The opening-to-body ratio is 1.38×, while the whole image is 6.48 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 5 enclosed loops and 3 main ink groups. The letterforms carry the main horizontal movement; there is no long lower underline detected beneath their band.

Leonhard Euler’s signature in graphology

Traditional graphology associates enlarged capitals with public emphasis. The clear abbreviation and word gap give a deliberate rhythm, while the connected surname maintains a flowing, comparatively restrained continuation.
