&lt;span class="commentBody"&gt;One component of its essence, or one way of looking at it, is constructing it by four tempered 3/2 each of which is divided&lt;/span&gt; in 5 tones, which in turn approximate 11/8 13/8 7/6 etc., and themselves end up on 5/1 the pentave. So calling it some kind of quintuple non-octave meantone makes a certain sense but it goes beyond that, as a temperament making use of the 2nd, 3rd, 5th, 7th, 11th, 13th harmonic factors and probably many more.</pre></div>
&lt;span class="commentBody"&gt;One way of looking at it comes by constructing it via four tempered 3/2 each of which is divided&lt;/span&gt; into five tones, which in turn approximate 11/8 13/8 7/6 etc., and themselves end up on the "pentave", 5/1. Adding octaves makes it [[Meantone family#Jerome]] temperament, with generator a meantone fifth divided in five, and Hieronymus is the generators of that. Jerome/Hieronymus only really comes into its own as a higher limit temperament, as a 13, 17, 19 or even 23 limit system.</pre></div>
