Polkan

Polkan in Slavonic tradition derives from the Italian literary figure Pulicane, a half-dog character in Andrea da Barberino's poem I Reali di Francia, which entered the Slavonic world through prosaic translations; Slavic reception reinterpreted the name by folk etymology as полуконь (polukon, "half-horse"), producing variant local conceptions. In the Bova Korolevich/Buovo narrative cycle Polkan appears as a distinct individual who confronts the hero, is overcome in combat, and thereafter is incorporated into the hero's household as a loyal guard and companion. In later popular usage the personal name "Polkan" became associated with guard dogs in the 19th century, reflecting the character's association with guardianship.

Sources report two principal, variant morphologies rather than a single standardized anatomy. In many Russian accounts and by folk etymology Polkan is described as half-human, half-horse (centaur-like); other variants preserve the Italian model as half-human, half-dog (a dog-man). The supplied materials do not provide detailed anatomical descriptions (such as coloration, dress, precise proportions, or facial details); the figure is presented as an individualized hybrid warrior whose exact physical traits vary between attestations.

The documented sources limit Polkan's powers to exceptional physical and martial qualities: immense strength, great speed, and notable combat skill. Narratively, he functions as a powerful non-human warrior-companion—initially an opponent of Bova Korolevich and then his loyal ally and protector. No supernatural faculties beyond extraordinary physical prowess (for example, magic, cosmological control, or spirit-possession) are recorded in the provided materials; his role is primarily martial and protective.
