Eglė the Queen of Serpents

Eglė the Queen of Serpents, alternatively Eglė the Queen of Grass Snakes, is a Lithuanian folk tale, first published by M. Jasewicz (M. Jasevičiaus) in 1837. The tale features not only human–reptile shapeshifting, but irreversible human–tree shapeshifting as well. Numerology is also evident in the tale, such as twelve sons, three daughters, three days, three tricks, three weeks of feast, nine years under the oath of marriage, three tasks given to Eglė by her husband to fulfill and nine days of visits.
