Laws of the Medes and Persians

Unalterable laws.

“Now, O king, … sign the writing, that it be not changed, according to the law of the Medes and Persians which altereth not.”—Daniel vi. 8.

The Laws of Howel Dha, who reigned in South Wales in the tenth century, printed with a Latin translation by Wotton, in his Leges Wallicæ (1841).
