I'd not heard it before, but it certainly has some usage in English Books.

the phrase also gets twenty(20) hits in OED online, including this gem: Thus God the great Induperator bespeaketh the Medes and Persians as his field-officers.

and this def'n [under law]: 1c. In proverbs and proverbial phrases. the law of the Medes and Persians, often used (with allusion to Dan. vi. 12) as the type of something unalterable.
