Brian MacDonald Antique Rugs & Carpets has dated this Antique Lori Bakhtiari Tacheh to the 1890s.

Opened up like this, shows how the tacheh was made on the loom, after which it was sewn up on both sides and base with goat-hair, leaving the top open into which the wheat was poured (see photos attached).
The knotted-pile, bottle-shape, central section symbolises the wheat being poured into the container.

This is a remarkable example of an archaic wheat-sack; a weaving that disappeared from nomadic life around the early 20th century and replaced by western plastic and gunny sacks which began to appear in the bazaars of Iran around that time. These sacks are a rare find these days.
