Babr-e Bayān

Accounts vary across epic interpolations and later traditions. In Shahnameh-derived interpolated verses and related epic material the item is presented as Rostam’s named outer suit worn in war. Some verses report the suit as made from the skin of a leopard (hence the alternative name Palangineh). In other interpolated or later narratives (reported in encyclopedic summaries) Rostam is said, at age fourteen in an account, to have slain a dragon called Babr-e Bayān in India — a sea-dwelling creature that came ashore only one day a week — and to have fashioned the suit from its hide. Sogdian texts and later tumar prose sometimes record or echo these variant origin tales. The element “Babr” is attested as meaning “tiger” in Middle Persian; “Bayān” is of uncertain origin and may represent a place-name or a proper name attached to the creature or object in different traditions.

The suit is described in the sources as a dark, hairy outer garment or armor. In leopard-skin accounts it is explicitly a feline-hide garment (Palangineh); in dragon-origin variants it is the hide of the slain monster. It functions as the outermost layer of Rostam’s layered defenses, placed last over other armorial garments such as the zereh and jowshan/gabr.

Sources ascribe a number of preternatural defensive properties to the suit: it is described as invulnerable (against fire, water, and ordinary weapons). It functions as Rostam’s ultimate layer of protection in battle, conferring near-complete protection when worn. The suit is treated as an empowering object rather than an autonomous agent; no sourced accounts attribute independent action or consciousness to it.
