An etching of Louis IV, Holy Roman Emperor. A bust length portrait in profile facing right, wearing a headband and mantle fastened at the shoulder. A Latin inscription and title on the 'plinth' of the sculptural portrait reads 'LUDOVICUS. IV.' An inscription in the upper right of the plate lists the object as being 'No. 125'. The print was originally included in Anton Ferdinand von Geissau's Geschichte der römischen Kaiser: mit ihren Bildnissen (1804-1807), which included a series of etched portraits of Roman Emperors by the printmaker Mark Quirin.
