In the 2007 Feb-Mar Ancient Egypt appeared an attack by John J. Wall upon an explicitly speculative DR theory (presented at the Greenwich centennary symposium, 1984) that the most important ancient Egyptian monuments may have been knowingly placed upon latitudes equal to unit-fractions of a circle. Wall's article classed this idea with “weird” science. He mailed the AE issue to DR anonymously. (Wall belongs to a contentious “Hall of Ma'at”, which resembles and has contacts with a DR-embarrassed smearer, CSICOP.)

Wall's analysis was so contemptuous, even while amateurishly bungled in its science, that DR wrote a detailed letter on 2007/4/7 to AE (and thus Wall) wondering how such a mess could have occurred — including Wall's mis-rendering a latitude “pinched from DR” (p.4). The letter's footnote 6 noted indication of another's involvement in the AE attack.

AE replied on 5/5 without offering an explanation or owning to having erred in any respect. Wall did not reply.

While posting a mercifully softened version of the 4/7 letter, DR on 2007/5/30 wrote his 2nd and last letter to AE, asking whether AE could specify any expert who had refereed the article and suggesting that Wall name the party who couldn't even read angles' endings correctly. Despite follow-up DIO email inquiry, no (direct) response has occurred from either AE or Wall.

Shortly after his 2007 Feb-Mar Ancient Egypt attempt to portray DR as crank, Wall made his debut (2007 May) in the DR-loathing Journal for the History of Astronomy.
