But whether Zaidan was devastated twice, or whether the two accounts apply to the same disaster, it is not easy to ascertain at so distant a date. There are obvious signs all over Eastern Sistan that the country must have undergone great trouble and changes—probably under the rule of Shah Rukh and his successors (a.h. 853-873), after which revolutions seem to have been rampant for some sixty years, until Shah Ismail Safavi conquered Khorassan and the neighbouring countries, founding a powerful dynasty which reigned up to the year a.h. 1135.
Under the Safavi dynasty Sistan seems to have been vested in the Kayani Maliks, who are believed to be descendants of the royal house of Kai. (I came across a village chief claiming to be the descendant of these Kayani rulers.)
To return to the Zaidan ruins, as seen to-day from the highest point of the citadel wall, the ruined city stretches in a curve from north to south-east. It is to the south-east that the ruins are less covered with sand and in better preservation, the citadel standing about half way between its former north and southern termini. There is every evidence to show that the present extensive ruins of Peshawaran to the north, Pulki, Deshtak (Doshak described by Bellew) and Nad-i-Ali were at one epoch merely a continuation of Zaidan the great city, just as Westminster, South Kensington, Hammersmith, &c., are the continuation of London, and make it to-day the largest conglomeration of houses in the world. It was evidently necessary to subdivide such an enormous place into districts.
