At the time when Sílim and Túr were killed, Tahmasp, the son of Sílim, fled from the country and took refuge in an island, where he died, and left a son named Zau. Zál sent Kárun, the son of Kavah, attended by a proper escort, with overtures to Zau, who readily complied, and was under favorable circumstances seated upon the throne: Speedily, in arms, He led his troops to Persia, fought, and won A kingdom, by his power and bravery-- And happy was the day when princely Zau Was placed upon that throne of sovereignty; All breathed their prayers upon his future reign, And o'er his head (the customary rite) Shower'd gold and jewels. When he had subdued the country, he turned his arms against Afrásiyáb, who in consequence of losing the co-operation of the Persians, and not being in a state to encounter a superior force, thought it prudent to retreat, and return to his father. The reign of Zau lasted five years, after which he died, and was succeeded by his son Garshásp. GARSHÁSP Garshásp, whilst in his minority, being unacquainted with the affairs of government, abided in all things by the judgment and counsels of Zál. When Afrásiyáb arrived at Túrán, his father was in great distress and anger on account of the inhuman murder of Aghríras; and so exceedingly did he grieve, that he would not endure his presence. And when Afrásiyáb returned, his sire, Poshang, in grief, refused to see his face. To him the day of happiness and joy Had been obscured by the dark clouds of night; And thus he said: "Why didst thou, why didst _thou_ In power supreme, without pretence of guilt, With thy own hand his precious life destroy? Why hast thou shed thy innocent brother's blood? In this life thou art nothing now to me; Away, I must not see thy face again." Afrásiyáb continued offensive and despicable in the mind of his father till he heard that Garshásp was unequal to rule over Persia, and then thinking he could turn the warlike spirit of Afrásiyáb to advantage, he forgave the crime of his son. He forthwith collected an immense army, and sent him again to effect the conquest of Irán, under the pretext of avenging the death of Sílim and Túr. Afrásiyáb a mighty army raised, And passing plain and river, mountain high, And desert wild, filled all the Persian realm With consternation, universal dread. The chief authorities of the country applied to Zál as their only remedy against the invasion of Afrásiyáb. They said to Zál, "How easy is the task For thee to grasp the world--then, since thou canst Afford us succour, yield the blessing now; For, lo! the King Afrásiyáb has come, In all his power and overwhelming might." Zál replied that he had on this occasion appointed Rustem to command the army, and to oppose the invasion of Afrásiyáb.
