Now that their system of computation has been explained, I shall proceed with their history. They say that when his attendants found not the auspicious monarch _Jaí Alád_, neither amongst his courtiers, nor in the royal apartments, or _harem_, nor in the house of praise, or place of prayer, the affairs of the human race fell once more into disorder: at length the sages and holy men went and represented the state of affairs to the praise-worthy apostle _Sháí Gilív_, son of _Jáí Alád_, who was then engaged in the worship of the Almighty. This prince, from his great devotion and unceasing adoration rendered to God, was called _Sháí_ and _Sháyí_, that is a god and a God-worshipper: his sons were therefore styled _Sháyián_. When the sages had stated the case, the first _Sháyíán_ prince, _Sháí Gilív_, having reflected on the cruelty practised towards the animal creation, arose, through the influence of a celestial revelation and Divine light, and sat in his illustrious father’s throne. After this happy dynasty came _Sháí Mahbúl_, when the _Sháíyán_ empire had lasted one _shamár_ of years. After these came the _Yásánián_, so called from _Yásán_, the son of _Sháí Mahbúl_: this prince was exceeding wise, intelligent, holy and celebrated; the apostle of the age: and being in every respect worthy of supreme power, was therefore called _Yásán_, or the meritorious and justly exalted.[248] His mighty sire having withdrawn from mankind, retired into seclusion, and there giving himself entirely up to the worship of God, the affairs of the human race again relapsed into disorder. Tradition informs us, that when these auspicious prophets and their successors beheld evil to prevail amongst mankind, they invariably withdrew from among them――as they could not endure to behold or hear wickedness; and sin had no admission to their breasts. When the chain of worldly repose had been rent asunder, Yasán, in obedience to a Divine revelation, seated himself on the throne of sovereignty, and overthrew evil. Of this happy dynasty the last was _Yásán Ajám_, when this admirable family had graced the throne during ninety and nine _salám_ of years. The author of the _Amíghistán_ says: “The years which I have mentioned are _farsáls_ of Saturn: one revolution of the regent Saturn, which is allowed to be thirty years, they call one day; thirty such days, one month; and twelve such months, one year.” This is the rule observed by the _Yezdánián_, who write down the various years of the seven planets after this manner: such is the amount of the saturnian _farsál_. This same system of computation is applied to the _farsáls_ of Mars, Venus, Mercury and the moon, a day of each being the time of their respective revolutions: they at the same time retain the use of the ordinary lunar and solar months.
