Trigone before 1828

"Trigone," a drawing by Pierre Félix van Doren, is a design for a musical instrument. The artwork depicts a triangular zither, a stringed instrument popular in the 19th century. The design features intricate details, such as the ribbons and the rosette at the base of the instrument. The artwork's clear lines and simple composition showcase van Doren's skill as a draftsman, and the instrument's design reflects the popular interest in the zither during the early 19th century.
