Description

Nomenclature


  • According to the IAU Planetary Gazetteer, this crater is named for Luigi Giglio (also known as Aloysius Lilius, unkn-1576), an Italian doctor, philosopher, chronologist, best known as a principal author of the Gregorian Calendar.
  • The name was introduced by Riccioli, however as noted by Whitaker the name listed in Riccioli's nomenclature list is Lilij fratres (presumably "Lilius brothers"), and the name Lilij (which Whitaker writes "Lilii") is printed on the map in such a way that it might have been meant to collectively label three craters, probably the modern Lilius plus its companions A and B (or C?). The Wikipedia article about Luigi Giglio mentions a brother, Antonio. Riccioli himself, in his chronology mentions Aloysius Lilius as having been active in 1582 (he had actually died by then) and also a Lilius Gregorius Gyraldus (active in 1542). In his biographical entry for Aloysius Lilius, Riccioli mentions that Aloysius worked jointly with his brother Antonius Lilius. This seems similar to the more modern case of Henry Frères, but since three craters may have been named, might there have been a third brother? - Jim Mosher
    • More information on Lilius is available in the Catholic Encyclopedia, where his correct unlatinized name is given as Aloigi Giglio, and Lilius Gregorius Giraldi is identified as an unrelated person.
    • Without being able to read Riccioli's mind it is difficult to know if he meant to name a single crater, or a group of three, and in either event, whether he intended to honor the two brothers, a third unknown brother or all three astronomically-related persons he knew of by the name of Lilus.
  • Lilius Alpha (the pronounced central peak of Lilius) (see charts 108 and 109 in the Times Atlas of the Moon, and page 148 in Tony Dethier's Maanmonografieen).
