notes: label: Description
content: Claudius Ptolemy (ca. 100 C.E. – ca. 170 C.E.), noted mathematician, astronomer, geographer and astrologer of Alexandria, described several instruments in his book, <i>The Almagest</i>. Among them was the triquetrum, a device for measuring the altitudes of astronomical objects. This reproduction was made in 1961 for display in the soon-to-be opened National Museum of History and Technology (now the National Museum of American History).
