The Žaltys is a spirit of Baltic tradition.
The grass snake at the hearth, guardian of luck and the milk blessing.
The Žaltys, Latvian zalktis, is the sacred house snake of the Balts: a harmless grass snake kept beneath the hearth that brings luck, prosperity and fertility. Killing it was considered a grave misfortune.
The cult is attested by a dense, at times eyewitness-close chain of sources from the 15th to the 18th century, among others Hieronymus of Prague, Długosz and Herberstein. In folklore, each cow has her own snake, and snake and child eat from the same milk bowl.

Baltic folk belief; the cult is attested by sources from the 15th to 18th centuries and survives in folklore.
Lithuania, Latvia and Old Prussia: throughout the Baltic region the grass snake was tolerated and honoured in the home.
Very well documented: a dense, at times eyewitness-close chain of sources from Hieronymus of Prague through Długosz to Herberstein, alongside the study by Luven.
Lithuanian: žaltys, Latvian zalktis. The etymology is disputed: a popular link connects it to Lithuanian žalias, green, referring to the green grass snake; linguistically, the dominant interpretation links the word to the Indo-European root for milk, which fits well with the milk-centred cult.
Appearance
The Žaltys is a harmless grass snake, kept beneath the hearth or stove, in the sacred corner by the table or in the stable, sometimes in a small willow basket. In folklore, every cow has its own snake, and snake and child eat from the same bowl of milk.
Effect
It brings luck, prosperity, fertility and a good harvest, guards the house, protects against thunder, illness and murder, and secures the cows’ milk flow. Milk offerings ensure its goodwill; neglect brings misfortune.
The key aspects of the house snake at a glance.
Sacred house snake of Baltic folk belief, with one of the region’s best-documented cults: milk feeding, hearth keeping, taboo on killing.

Luck, fertility and a blessing of milk; protection from thunder, illness and murder for the household that honours the snake.
Milk in a bowl at the centre of the house; killing or mistreating the snake is consistently regarded as a grave offence with disastrous consequences.
The Roman house snake in the cult of the Lares and Penates and the Greek Agathodaimon; in the Baltic region the Kaukas and Aitvaras stand alongside it.
The etymology of the name is disputed: a popular link connects it to Lithuanian žalias, green, referring to the green grass snake; linguistically, the dominant interpretation links the word to the Indo-European root for milk, and it fits remarkably well with the milk-centred cult.
The cult itself is among the best attested in the Baltic region: a dense, at times eyewitness-close chain of sources from the 15th to 18th centuries runs from Hieronymus of Prague through Długosz to Herberstein. It describes the snake beneath the hearth, the bowl of milk at the centre of the house, and the taboo that links its killing to misfortune, from the death of a child to the drying up of milk.
The Žaltys is a national cultural symbol of Lithuania. The tale Eglė žalčių karalienė, Eglė the Queen of Serpents, first printed in 1837, is the best-known Lithuanian narrative and combines the motifs of snake, tree and transformation; in Baltic neopaganism, the snake is central.
From a religious-studies perspective, the Žaltys is a sacred, benevolent house snake. Three clarifications are important: milk feeding, hearth keeping and the taboo on killing are excellently documented. The frequently cited link to the sun goddess Saulė, said to mourn a killed snake, is by contrast a modern interpretation, chiefly associated with Gimbutas, and is not attested in the early modern period. And the etymology remains uncertain.
The cult of the Žaltys is one of care, not warding off: milk is placed for the snake in a bowl at the centre of the house, and it is kept by the hearth. Killing or mistreating a house snake is consistently regarded as a grave offence with disastrous consequences, from the death of a child to the drying up of milk; this taboo on killing is one of the best-documented features of the entire cult.
Early modern authors already compared the Žaltys to the Roman house snake in the cult of the Lares and Penates and to the Greek Agathodaimon. Within the Baltic region it stands alongside the Kaukas and the Aitvaras as a bringer of household blessing; in Korea, too, a snake, Eopsin, watches over the house.

As both a Lithuanian house snake and a sacred grass snake, the Žaltys shows how closely everyday life and cult were interwoven in the old Baltic region: an animal by the hearth became the guardian of luck, milk and home.
