This opinion was occasionally repeated both in France and Germany down to the close of the eighteenth century. Early in that century, however, the materials for forming a more accurate judgment began rapidly to accumulate. The three travellers Chardin, Kaempfer and Le Bruyn all made important contributions to the subject. Chardin was the son of a rich jeweller in Paris, and early in life he was sent on business to Persia and India. On his return in 1681 he settled in England and was knighted by Charles II., who afterwards sent him to Holland as his ambassador. Chardin’s three visits to Persepolis were made as far back as 1666, 1667 and 1674, but his account of it did not appear till 1711. It was published at the same time in two different forms: in three volumes quarto and in ten volumes duodecimo, but with the same text and plates. This edition was somewhat expurgated to avoid giving offence to the Catholics, but another came out in 1735, which included the suppressed passages. Chardin died in London in January 1713, two years after the publication of the complete edition of his Travels, but before he had time to finish the most cherished work of his life, which was a Commentary on the Bible, based upon his knowledge of Oriental customs. It is said he was assisted in the composition of his works by Charpentier, a Member of the French Academy, and the magnificent drawings, twenty-three in number, made of Persepolis, are the work of M. Grélot, whom he brought with him for the purpose.[56] They convey a most admirable impression, and the student can for the first time realise the splendour of the ruins: which he could never have grasped from the confused description of travellers.
