The dimensional nature of this lowercase letter “a” monogram—comprising surface, volume, interior, and exterior—speaks to Arcsine’s comprehensive architectural practice. The subtext of this design is one of perception and, by extension, vision. The Arcsine wordmark is based on a face by Swiss designer Walter Käch and published in his book Schriften Lettering Ecritures in 1949.

The design of the Arcsine monogram came through an iterative sketching process. The form of the letter originates in the triskelion, an ancient “three-legged” glyph that symbolized progress and victory to the Greeks.
