A monument, perhaps to a musician, and dated mcccclxxiii, which is 1473; this art was made over 500 years ago. The bas-relief sculpture depicts a man wearing (of course) mediaeval costume (OK, medieval costume), playing perhaps a hand organ, and surrounded by other instruments, including harp and lyre. If you can work out who is to be remembered, please let me know and I will add that here. The various accents are scribal abbreviations, and indicate missing letters.
