Eagle 53 is identical to Euler's Genus Diatonico-chromaticum and Ellis' [[Duodene]], except that those used 45/32 instead of 7/5 in their just version.

This similarity is by coincidence and may simply speak to the fact that this is a useful and relatively simple scale that theorists are likely to land upon over and over, much like [[2L 3s]] or like 53edo itself.
