The Throne of Solomon neighbours until the Assassins began to take over their lands and much of their reputation in the twelfth century. The connection between Kalar and the Daylamites is given by the fact that the geographer Yaqut describes the town as being at one day's march from Chalus on the coast; two days from Ray (near Teheran); three from Amul on the east; and one day from the Daylamite frontier. From the plain of Kalar the only probable dividing line to fulfil these conditions is that of the Hazarchal Pass: Darijan—the other valley—could never be considered a day's ride, and all north of it—i.e. west or north- west of Kalar—is thick jungle until one reaches Daku, a two days' journey. The Hazarchal leads to the upper Talaghan valley, which is mentioned in the tenth century as part of the Daylam country, and Kalar would naturally be described as being at one day's distance from that fertile region: it would be equally accurately described as being close to the Daylam- ite fastnesses of the western jungle: in either case die site of Kalar fits the geographical requirements, and answers also to numerous references made by the historians of those times. Yaqut also mentions the little town of Sa'idabad as close to Kalar, on the way between Hasankeif and Laktar, which latter village still exists in Kujur. Hasankeif, though not marked on the maps, is now the capital of Kalar Dasht, almost in sight of Rudbarek. The track from Kalar to Ruyan would also be the track from Hasankeif to Laktar, along the Pul Rud valley, where Sa'idabad must be looked for. I have gone into these references because they form the basis for the geography of Kalar.1 But at the time, I had no books packed in my saddle-bags. All I remembered was the impor- tance of Kalar in connection with the Daylamites, for if this were really the site of the old city, then we had probably 1 For a mote detailed study see my article ; " The Site of Kalar " in the Royal Geographical Society Journal for March, 1934.
