This is a black and white engraving depicting a man playing a large, unusual stringed instrument. The man is seated on a rock, with one leg crossed over the other. He is dressed in 17th or 18th-century attire, including a long-sleeved jacket with multiple buttons, a ruffled collar, and what appears to be a waistcoat. He has long, curly hair and is looking towards the viewer. The instrument he is playing is quite large and resembles a cello, but it has a unique shape and only one string. It is held vertically and is supported by a stand. The instrument is intricately detailed with carvings and embellishments. Below the image, there is text that reads "LXI Monocordo". In the upper right corner, there is a number "103". The background is filled with closely spaced vertical lines, creating a textured effect. The overall style of the engraving is reminiscent of historical illustrations or portraits.
