    1) "In this detailed history, Aczel (God's Equation; Bentley Coll.) takes us back in time to Amalfi, Italy, where between 1295 and 1302 the compass as we know it was developed. Aczel points out, however, that the actual discovery of materials that followed magnetic lines, or at least consistently pointed in a specific direction (south), is attributed to the Chinese in 1040."

    2) "The find of an Olmec hematite artifact, fitted with a sighting mark and found in experiment as fully operational as a compass, has led the American astronomer John Carlson after radiocarbon dating to conclude that "the Olmec may have discovered and used the geomagnetic lodestone compass earlier than 1000 BC". Carlson suggests that the Olmecs may have used such devices for directional orientation of the dwellings of the living and the interments of the dead."
