This comma was first named as ''tertiapont'' by [[Gene Ward Smith]] in 2005 as a contraction of ''[[tertiaseptal]]'' and ''[[pontiac]]''<ref>[https://yahootuninggroupsultimatebackup.github.io/tuning-math/topicId_12900.html Yahoo! Tuning Group | ''Seven limit comma names from pairs of temperament names'']</ref>. It is not clear how it later became ''horwell'', but the root of ''horwell'' is obvious, being a contraction of ''[[hemithirds]]'' and ''[[orwell]]''. | |||
