NeugebauerO. and ParkerR., Egyptian astronomical texts, i (Rhode Island, 1960), 26–28. This work is the major reference for diagonal star clocks. Neugebauer and Parker labelled their twelve sources Coffin 1, Coffin 2, etc. This form has become cumbersome with the addition of more sources. Coffin designations following L. Lesko, Index of the spells on Egyptian Middle Kingdom coffins and related documents (Berkeley, 1979), will be used in the current paper, but Neugebauer and Parker's numbers will be also be noted for ease of cross reference.

LeitzC. in Altaegyptische Sternuhren (Leuven, 1995), without knowledge of EA47605, calculated it to be highly unlikely that all the knmt group tables omitted the date row by chance.
