bahhdi

Bactria was a country which enjoyed the reputation of having been great and glorious at a very early date. In one of the most ancient portions of the Zendavesta it was celebrated as "Bahhdi eredhwo-drafsha," or "Bactria" with the lofty banner; and traditions not wholly to be despised made it the native country of Zoroaster.
