Varnished brass Ptolemaic armillary sphere acquired and restored in the second half of the nineteenth century by Ferdinando Meucci, director of the Museo di Fisica e Storia Naturale of Florence. The Earth is represented by a small brass sphere at the center. Two embossed brass circles carry the Moon and Sun. The names and zodiac signs are in Latin. The initials S.A.C.—in all likelihood the maker's—have not been identified.
