The mirror image, or inversion, of the above entry [clockwise spiral] symbolizes, like that ideogram, /rotation/. It stands first and foremost for a /counterclockwise rotation/ and is therefore related to [counterclockwise swastika]. This sign appeared in the Euphrates cultures as early as around 2000 B.C., and [counterclockwise spiral] is an Egyptian hieroglyph for /thread/ or /measurement/. [Angled counterclockwise spiral] was used in the earliest Chinese ideography with the probable meaning /return/ or /homecoming/. The Hopi Indians seem to have given it the same meaning. [...] The sign was used by the Phenicians and as a pattern on Bronze Age jewelry found in Scania, Sweden, dating back to about 1300 B.C. Compare with the hieroglyph [straight-line spiral with four angles], representing /Egypt/, i.e., that country that one /returns to/, the /homeland/. There is a similar usage in the English system of hobo signs: a /good house for work/, i.e., a place that is worth returning to when one needs food and money. The sign [somewhat straightened spiral] is found painted on the walls of houses in Tibet [...] and has perhaps the meaning /home/, the place one returns to. It can also signify /whirlpool/ or /eddy/ on nautical charts. (Liungman, Carl G.: Dictionary of Symbols, W. W. Norton & Company Ltd, 1991 (English translation of original from 1974))
