    • 1553, Luminarum atque Planetarum motuum Tabulae octogina quinque, omnium ex his quae Alphonsum sequuntur quam faciles[1]:
      Motus, seu locus, per signa, gradus, minuta, et secunda constitutus, intelligitur (secundum regulam Alphonsi) signa physica, id est quodlibet signum ex 60 gradibus compositum, et quilibet gradus ex 60 minutis, et quodlibet minutum ex 60 secundis, et sic succesivem: et per consequens, sex signa totum circulum perficiunt.
      A motion, or location, for a sign, being composed of degrees, minutes, and seconds, is understood (according to the rule of Alphonse) to be a physical sign, that is, every sign is composed of 60 degrees, and every degree of 60 minutes, and every minute of 60 seconds, and so on and so forth: and in consequence, six signs make up an entire circle.
