Van Langren's names and Greek letter designations

From The Moon
Jump to: navigation, search
This sub-page is an exploration of Michel Florent Van Langren's names for small mountains, hills, and hillocks (which received Greek letter designations during the era of Mary Blagg's NAMED LUNAR FORMATIONS). Nowadays these Greek letter designations are not official anymore (digital atlases such as the LROC's Act-React Quick Map don't show them), but... certain printed lunar atlases such as the TIMES ATLAS OF THE MOON (1969) still show many of these designations (unfortunately not all of them).
Now, the nomenclature lists of M.F.Van Langren, J.Hewelcke, and G.B.Riccioli in Ewen A. Whitaker's book MAPPING AND NAMING THE MOON also show a lot of these Greek letter designations. One could only guess how Whitaker got all of these designations. Perhaps from Mary Blagg's N.L.F.?

The Aytona=Nachara / Silgero=Piperii mystery

What happened during the making of Van Langren's map? According to E.A.Whitaker, two sections of the system of mountains officially known as Montes Harbinger seem to have been moved to the northeast and were called Nachara and Piperii. At their "southwest" locations they were called Aytona and Silgero.
Indeed, on Van Langren's map there are two couples of named formations. Couple 1 shows Aytona and Silgero, couple 2 shows Nachara and Piperii.
