I visited a small tomb whilst at Mârâgâ, in which, according to common report, the remains of Hoolakoo are interred, as also those of his Christian queen Delghooz Khâtoon. To this lady, even Mahomedan writers ascribe some of the most munificent actions of her Moghul lord, who was attached to her in a very extraordinary degree. She is reputed to have been a great proficient in science, and to have honoured with her peculiar patronage and favour the celebrated Naser-ood-Deen, of whom I have already spoken. The reputation of this great man had nearly proved his ruin. A young chief, of a gloomy disposition, belonging to the dreaded sect of Hoosein, who dwelt in the north-western mountains of Persia, having heard of his fame, and thinking to profit by his wisdom, commanded that he should be brought to his presence. The mandate was instantly obeyed; for his followers gave a devoted obedience to their chief, being fanatics of the same sect as the subjects of the Old Man of the Mountain,[161] whose history is familiar to all readers of the wars of the crusades. A few men were sent in disguise to Bokhara, and Naser-ood-Deen was seized and carried off while walking in his garden. He was made over from one party to another, till he found himself at the "Eagle's Nest:" so the residence of the young prince, on the top of a high mountain, was called. His value, we are told, was fully appreciated at this barbarous court. While, however, they honoured him with every attention, they took precautions to prevent all possibility of escape. It was during this confinement that he wrote the celebrated treatise on ethics,[162] which has raised his fame as high for philosophy as for astronomy. The desire of liberating a genius of whom his country was justly proud, was, we are told, one of the principal motives which led Hoolakoo to attack and destroy this abode of dreaded assassins;[163] and when their boasted Eagle's Nest was taken, the emperor rejoiced less in its capture, than in having released Naser-ood-Deen, who was immediately invested with a dress of honour, and promoted to high employment. But it was to the favour and patronage of the Christian princess Delghooz Khâtoon, that this philosopher owed the opportunities he enjoyed at Mârâgâ, of making his name coeval with that of oriental science. No less than five of my friends, who had been long absent on their travels, joined us at Mârâgâ. Four of them I could hardly recognize, being dressed in Persian clothes, and having large whiskers and long beards. They told us wondrous tales of Seestan, Balochistan, Hamadân, and other countries in which they had been. We were now a party of fourteen, but we did not remain long together: some were detached to drill Persian soldiers, while others were sent to survey and report upon the soil and population of different districts of this once famous kingdom.
