+To the [[wizma]] {{monzo| -6 -8 2 5 }} = 420175/419904, the kalisma is a natural complement, as their product is the [[argyria]], {{monzo| -9 -4 0 3 2 }} = 41503/41472. [[User:VIxen|VIxen]] named it and [[#Gersemi|gersemi]] after Odr's and Freya's daughters since in 11-limit, they both temper out one comma of [[odin]] (9801/9800) and one of [[freya]] (41503/41472). There is also a word play on "semi-" that hints at the split of the octave in half.

+=== Gersemi ===
+The extension to 13-limit with [[4225/4224]] is weak but facilitates the use of 18/7 as the equave. [[Fokker block]]s of 128 notes are available for the latter, corresponding to 94edo. 18/7 is split into 4 parts that become ~19/15 in 19-limit. Also, (18/7)<sup>3</sup> ~ 17/1 via the [[5832/5831|chlorisma]]. However, the tones 9/8 and (19/15)/(9/8) = 152/135 have distinct mappings.

+== Rishi ==
+The 7-limit comma {{monzo| 65 -84 10 16 }} ~ 0.13¢ has the ratio of the exponents of 3 and 2 that is close to the one in 81/8. The square root of the latter is close to 35/11. This suggests tempering out (81/8)(35/11)<sup>-2</sup>, which is the kalisma.
+Apart from 35/11, 35/33, and the equivalents of their squares, 81/8 and 9/8, another equave that comes to mind is 3/2, especially after tempering out the [[chalmersia]]. When 3/2 is chosen as the equave, Fokker blocks of 34 notes can be used that are close to [[34edf]] and 58edo.
+When [[User:VIxen|VIxen]] was naming this temperament, [[sruti]] was its only named rank-2 subtemperament. Rishis (sages) are believed to have created shruti texts.
