The peculiar "amphi-theatre" shaped Harriot was captured near the lower part of the right margin of Apollo 16's Fairchild-camera frame AS16-M-3001, which was made during TEC (Trans Earth Coast).

It should be mentioned: investigating this (rather unknown) part of the lunar farside with help of P.Spudis's and B.Bussey's Clementine Atlas of the Moon (LAC 30, page 61) is quite an adventure! - DannyCaes Nov 5, 2012

- There is a large amount of literature related to Harriot - some of the principal references are listed to Allan Chapman in the Bibliography section below.
- Harriot's lunar observations had been mentioned as early as 1784/1785 by Baron Zach. A more extensive account of Harriot's papers, including an explanation of Zach's involvement, appeared in Rigaud's Supplement:
- Named for Thomas Harriot (1560-1621), a British mathematician and astronomer. Harriot is generally credited with having made the oldest surviving sketches of an astronomical object -- in this case the Moon -- as seen through a telescope.
- Three of his original drawings were on display at an exhibit honoring 400 years of the telescope.
- His observations were made from Syon House, near Kew Gardens, in London. His earliest drawing is dated July 26, 1609 on the Julian calendar then in use in England, or August 5, 1609 on the modern Gregorian calendar, at 9 hours after noon. The later drawings include a numbered and lettered full disk map, but it is not known if Harriot applied names to the numbered or lettered features. Whitaker (p. 57) mentions a 14 Dec 1611 reference (in Harriot's papers) to this map, so it was evidently completed sometime before that date. Whitaker (pp. 7 and 17) believes the only names Harriot associated with lunar surface features were pre-existing traditional ones based on naked eye observation.
- An excellent copy of Harriot's first sketch can be found here. The "6/1" notation in the lower right refers to the magnification produced by his telescope. For comparison, here is a digital simulation of how the Moon would have looked at that hour, created using the LOLA altimeter data shaded with the Clementine intensities. The simulation shows the Moon as seen from Syon House, but has been rotated 90° CCW to correspond more closely to the drawing.
