WARNING: the name Theophilus is mentioned on many orbital frames of Apollo 12's three stereo-strips 56-B, 56-C, and 56-D. In fact, most of these frames don't show Theophilus at all! All the frames of these three stereo-strips show the same caption: DESCARTES - LALANDE - MCCLURE - THEOPHILUS (which seem to have been four of the most important "landmarks" on these stereo-strips).- DannyCaes DannyCaes Aug 15, 2010

Chesley Bonestell's painting of Theophilus
In Willy Ley's book The Conquest of Space (1951), there's a wonderful painting made by Chesley Bonestell which shows a southward oblique view of Theophilus and nearby craters Madler, Cyrillus, and Catharina. This painting looks very much like one of Apollo 16's southward oblique looking orbital mapping/metric camera photographs made in april 1972. The sun's illumination in the painting, however, shows the lunar landscape during the pre-sunset hours, while Apollo 16's photographs of the same region show it during the post-sunrise hours. In the Dutch translated version of Willy Ley's book (De Sprong in het Heelal)(1951, translated by J. De Groot) this painting was printed as Plate XIXa, between pages 38 and 39. I don't know if the original book (The Conquest of Space) shows it at the same plate-number and between the same pages (?).

Description: Elger
(IAU Directions) THEOPHILUS.--The most northerly of three of the noblest ring-mountains on the visible surface of the moon, situated on the N.W. side of the Mare Nectaris. It is nearly 64 miles in diameter, and is enclosed by a mighty rampart towering above the floor at one peak on the E. to the height of 18,000 feet, and at two other peaks on the opposite side to nearly 16,000 and 14,000. The border, though appearing nearly circular with low powers, is seen, under greater magnification, to be made up of several more or less linear sections, which give it a polygonal outline. It is prominently terraced within, the loftier terraces on the E. rising nearly to the height of the crest of the wall, and including several craters and elongated depressions. On the E. glacis is a row of large inosculating craters; and near its foot, S.W. of Madler, a short unrecorded rill- valley. The magnificent bright central mountain is composed of many distinct masses surmounted by lofty peaks, one of which is about 6,000 feet above the floor, and covers an area of at least 300 square miles. Except a distinct crater on the S.E. quarter, this appears to be the only object within the ring.

Lunar Ellipse of Fire
The rim of Theophilus is (or was?) number eight in the list of 12 localities in the Lunar Ellipse of Fire (see article from Farouk El-Baz in Sky and Telescope - June 1973).
Nomenclature
Theophilus of Alexandria, (died 412) was the Nicene Pope of Alexandria, Egypt (385 - 412). He is regarded as a saint by the Coptic Church.
The cluster of central peaks at Theophilus seems to have been called Theophilus Alpha, Theophilus Phi, and Theophilus Psi.
