Pietro della Valle, at the time of his sojourn in Persia, studied them closely, and this is what he has to say: "These past few days I have been to see their new town [37] (that of the Gaures), or, let us say, their separate habitation, which, like the new Ciolfa inhabited by the Christian Armenians, like the new Tauris, or Abbas-Abad, where dwell the Mahomedans brought from Tauris, adjoins Ispahan, just as if it were a suburb; and although, at present, it is separated from it by some gardens, nevertheless with time,--for the number of inhabitants greatly increases every day,--Ispahan and this habitation of the Gaures>, with the two others aforesaid, will make but one place. I am therefore doubtful whether to call them separate citadels, or suburbs, or rather considerable parts of this same town of Ispahan, as is the region beyond the Tiber and our city of Rome. This habitation of the Gaures has no other name that I know of except Gauristan; that is to say, according to the Persians, 'the place of the infidels,' just as we call the quarters of the Jews, Jewry. This place is very well built; the streets are wide and very straight, and much finer than those of Ciolfa, for it was built later with more design; but all the houses are low and one-storied, without any ornament, quite consistent with the poverty of those that occupy them, and in this respect very different from the houses of Ciolfa, which are very magnificent and well planned; for the Gaures are poor and miserable,--at least they show all possible signs of being such; in fact, they are employed in no traffic; they are simply like peasants,--people, in short, earning their livelihood with much labour and difficulty. They are all dressed alike, and in the same colour which resembles somewhat brick cement." (Voyages, French translation, Paris, 1661, vol. ii. p. 104.) About the same time (1618), Figueroa, the ambassador of Philip III. in Persia, remarks as follows: "In the most eastern part of Persia, and in the province of Kirman, which forms its frontier to the east, there have remained some of those ancient and true Persians, who, although they have mixed with the others, and by uniting themselves to their conquerors, have become like one people, all the same retain their primitive mode of living, their customs and their religion. Thus, at this day, they adore the sun as did the ancient Persians during the period their empire was the first in this world, and, following their example, they invariably keep in their houses a lighted fire, which they keep up unextinguished with as much care as the Vestal Virgins of Rome did." (The Embassy of Don Garcias de Silva de Figueroa in Persia. Trans. Wicquefort, Paris, 1667, in 4to, p. 177.)
