Kaukas

Kaukas belongs to Lithuanian and wider Baltic household tradition. The descriptions vary between a small bearded man, a goblin-like figure, and a fiery trailing serpent or dragon seen flying at night — the last of these being the form in which it is said to travel, carrying what it has taken. It attaches itself to a household and enriches it, and the enrichment is understood to come from somewhere: grain and money arrive from neighbours' stores.

The relationship follows the pattern common to such spirits. It must be fed and kept properly, often with specific food set aside for it, and the household that neglects it loses both the spirit and the prosperity. It guards what it has accumulated, and the traditions connect it with buried treasure and with the sudden unexplained wealth of particular families — an explanation which had obvious social uses in a village.

Christian-era material recast such spirits downward, and the name appears in older sources in connection with a wider range of beings, including references to earth-dwelling and to the dead. The Baltic material was recorded relatively late and with mixed intentions, so the boundaries between kaukas and related household and treasure spirits are not sharp.

The paragraphs below are extrapolated; no source supports them.

Read as a personality, Kaukas comes across as industrious and entirely amoral — a spirit that works hard on behalf of whoever keeps it properly and is wholly indifferent to where the benefit comes from. There is nothing grand about it: the scale is grain and coins, the loyalty is to the household rather than to a person, and the arrangement ends the moment the feeding stops. The treasure-guarding strand suggests something acquisitive on its own account as well.
