Left: LO-IV-191H The names Mare Crisium Delta and Mare Crisium Epsilon (which appeared in Named Lunar Formations) were dropped by the IAU. The names Promontorium Lavinium, Promontorium Olivium and Glaisher X (which appeared in the System of Lunar Craters), no longer appear in the IAU Planetary Gazetteer. The craters partially visible along the left and right edges of this image are Proclus (left) and Yerkes (right). Glaisher is visible at the bottom. See Promontorium Olivium for the confusion about the arrows pointing to it and Mare Crisium Epsilon.
Right: Two LROC views (WAC No.'s M119530553ME and M117169050ME) of the region under different lighting conditions. Both images calibrated by LROC_WAC_Previewer.

Although not mentioned in the LPI's list, it (Promontorium Lavinium) WAS photographed during the Apollo program! - DannyCaes May 8, 2010
- Apollo 17's orbital ITEK-panoramic frame AS17-P-2259 and its stereo-companion AS17-P-2264 show Promontorium Lavinium near the left margins of both frames (one doesn't have to scroll to the right, the promontorium is immediately detectable).

Bounding the tiny break in the western rim of the Crisium Basin are two headlands that almost meet. To the north is the area east of the crater Proclus P, and to the south is the eastern wall of Glaisher X. Each of these headlands was named in the late 1800's by the English selenographer William Birt. He called the northern one Promontorium Olivium and the southern Promontorium Lavinium. Both of these names were included in Named Lunar Formations and in the System of Lunar Craters, but do not appear in the current list of IAU names. Prom. Olivium is broad and flatly rounded in cross-section, it appears to be the continuation of the Crisium Basin rim. Prom. Lavinium is narrower with a more V-shaped profile - it casts the more dramatic shadow under low illumination. These are conspicuous landmarks and these names should be re-instated.

Additional Information


  • The name Promontorium Lavinium appeared both in the Collated List (1913) and in Named Lunar Formations (1935, where it was Catalog #100). It also appears on maps A3 and A4 of the System of Lunar Craters, but it was not labeled on the contemporaneous LAC maps, and does not appear in later lists of IAU-approved nomenclature. However, it also does not appear on any published list of deletions, and does not appear to have been formally dropped.
