Mokosh appears once in the primary medieval record: as the sixth and only female idol Vladimir installs on the Kiev hill in 980, alongside Perun, Khors, Dazhbog, Stribog, and Simargl, per the Russian Primary Chronicle. The chronicle gives no myth, temple, or festival for her; everything beyond her name and her place in that list is inference or later folklore.
Two competing etymologies
Philologists disagree on her name's origin. Max Vasmer and others have proposed a link to the Finnic Moksha (a Volga-Finnic people neighboring the early Rus'), implying a borrowed cult; other scholars prefer a native Slavic root *mok- ("wet"), reading her as a moist-earth or mother-earth figure paired conceptually with the sky. Neither theory is settled.
Folk survival
East Slavic peasant belief recorded by 19th-century ethnographers kept a household spirit called Mokosha or a folk figure tied to spinning, sheep-shearing, and women's domestic ritual, and forbade leaving wool unspun overnight for fear of her displeasure. This is genuine, well-documented folk belief, but it is 19th-century ethnography, not a description of Vladimir's goddess — the line between them cannot be drawn with confidence.
Source Notes
These records lack edition and translator details. Their wording has not been verified as a direct quotation.
And he set up idols on the hill [...] and Mokosh.

Worship Practices
No medieval festival or rite is recorded for Mokosh. Later East Slavic folk custom (recorded by 19th-century ethnographers, not a pagan-era source) forbade women from spinning wool on her associated day, a taboo folklorists connect to her name but cannot trace back to the pagan period with certainty.
