The Building of Jaipur: Work in Astronomy.—As a statesman, legislator, and man of science, the character of Sawai Jai Singh is worthy of an ample delineation,[[2]] which would correct our opinion of the genius and [357] capacity of the princes of Rajputana, of whom we are apt to form too low an estimate. He was the founder of the new capital, named after him Jaipur or Jainagar, which became the seat of science and art, and eclipsed the more ancient Amber, with which the fortifications of the modern city unite, although the extremity of the one is six miles from the other. Jaipur is the only city in India built upon a regular plan, with streets bisecting each other at right angles.[[3]] The merit of the design and execution is assigned to Vidyadhar, a native of Bengal, one of the most eminent coadjutors of the prince in all his scientific pursuits, both astronomical and historical. Almost all the Rajput princes have a smattering of astronomy, or rather of its spurious relation, astrology; but Jai Singh went deep, not only into the theory, but the practice of the science, and was so esteemed for his knowledge, that he was entrusted by the emperor Muhammad Shah with the reformation of the calendar. He had erected observatories with instruments of his own invention at Delhi, Jaipur, Ujjain, Benares, and Mathura, upon a scale of Asiatic grandeur; and their results were so correct as to astonish the most learned.[[4]] He had previously used such instruments as those of Ulugh Beg (the royal astronomer of Samarkand), which failed to answer his expectations.[[5]] From the observations of seven years at the various observatories, he constructed a set of tables. While thus engaged, he learned through a Portuguese missionary, Padre Manuel, the progress which his favourite pursuit was making in Portugal, and he sent “several skilful persons along with him”[[6]] to the court of Emanuel. The king of Portugal dispatched Xavier de Silva, who communicated to the Rajput prince the tables of De la Hire.[[7]] “On examining and comparing the calculations of these tables (says the Rajput prince) with actual observation, it appeared there was an error in the former, in assigning the moon’s place, of half a degree; although the error in the other planets was not so great, yet the times of solar and lunar eclipses he[[8]] found to come out later or earlier than the truth by the fourth part of a ghari, or fifteen pals (six minutes of time).” In like manner, as he found fault with the instruments of brass used by the Turki astronomer, and which he conjectures must have been such as were used by Hipparchus and Ptolemy, so he attributes the inaccuracies of De la Hire’s tables [358] to instruments of “inferior diameters.” The Rajput prince might justly boast of his instruments. With that at Delhi, he, in A.D. 1729, determined the obliquity of the ecliptic to be 23° 28´; within 28´´ of what it was determined to be, the year following, by Godin. His general accuracy was further put to the test in A.D. 1793 by our scientific countryman, Dr. W. Hunter, who compared a series of observations on the latitude of Ujjain with that established by the Rajput prince. The difference was 24″; and Dr. Hunter does not depend on his own observations within 15″. Jai Singh made the latitude 23° 10´ N.; Dr. Hunter, 23° 10´ 24″ N.
From the results of his varied observations, Jai Singh drew up a set of tables, which he entitled Zij Muhammadshahi, dedicated to that monarch; by these, all astronomical computations are yet made, and almanacks constructed. It would be wrong—while considering these labours of a prince who caused Euclid’s Elements, the treatises on plain and spherical trigonometry, ‘Don Juan,’ Napier on the construction and use of logarithms, to be translated into Sanskrit—to omit noticing the high strain of devotion with which he views the wonders of the “Supreme Artificer”; recalling the line of one of our own best poets:[[9]]
An undevout astronomer is mad.
The Rajput prince thus opens his preface: “Praise be to God, such that the minutely discerning genius of the most profound geometers, in uttering the smallest particle of it, may open the mouth in confession of inability; and such adoration, that the study and accuracy of astronomers, who measure the heavens, may acknowledge their astonishment, and utter insufficiency! Let us devote ourselves at the altar of the King of Kings, hallowed be his name! in the book of the register of whose power the lofty orbs of heaven are only a few leaves; and the stars, and that heavenly courser the sun, small pieces of money, in the treasury of the empire of the Most High.
“From inability to comprehend the all-encompassing beneficence of his power, Hipparchus is an ignorant clown, who wrings the hands of vexation; and in the contemplation of his exalted majesty, Ptolemy is a bat, who can never arrive at the sun of truth: the demonstrations of Euclid are an imperfect sketch of the forms of his contrivance.
“But since the well-wisher of the works of creation, and the admiring spectator of the works of infinite wisdom, Sawai Jai Singh, from the first dawning of reason in his mind, and during its progress towards maturity, was entirely devoted to the study [359] of mathematical science, and the bent of his mind was constantly directed to the solution of its most difficult problems; by the aid of the Supreme Artificer, he obtained a thorough knowledge of its principles and rules,” etc.[[10]]
Besides the construction of these objects of science, he erected, at his own expense, caravanserais for the free use of travellers in many of the provinces. How far vanity may have mingled with benevolence in this act (by no means uncommon in India), it were uncharitable to inquire: for the Hindu not only prays for all those “who travel by land or by water,” but aids the traveller by serais or inns, and wells dug at his own expense, and in most capitals and cities, under the ancient princes, there were public charities for necessitous travellers, at which they had their meals, and then passed on.
Assassination of Farrukhsiyar, May 16, 1719.
Enough has been said of his public life, in that portion of the Annals of Mewar with which he was so closely connected, both by political and family ties. The Sayyids, who succeeded to power on the murder of their sovereign Farrukhsiyar, were too wise to raise enemies unnecessarily; and Jai Singh, when he left the unhappy monarch to his fate, retired to his hereditary dominions, devoting himself to his favourite pursuits, astronomy and history. He appears to have enjoyed three years of uninterrupted quiet, taking no part in the struggles, which terminated, in A.D. 1721, with Muhammad Shah’s defeat of his rivals, and the destruction of the Sayyids [360]. At this period Jai Singh was called from his philosophical pursuits, and appointed the king’s lieutenant for the provinces of Agra and Malwa in succession: and it was during this interval of comparative repose, that he erected those monuments which irradiate this dark epoch of the history of India.[[12]] Nor was he blind to the interests of his nation or the honour of Amber, and his important office was made subservient to obtaining the repeal of that disgraceful edict, the jizya, and authority to repress the infant power of the Jats, long a thorn in the side of Amber. But when, in A.D. 1732, the Raja, once more lieutenant for Malwa, saw that it was in vain to attempt to check the Mahratta invasion, or to prevent the partition of the empire, he deemed himself justified in consulting the welfare of his own house. We know not what terms Jai Singh entered into with the Mahratta leader, Bajirao, who by his influence was appointed Subahdar of Malwa; we may, however, imagine it was from some more powerful stimulant than the native historian of this period assigns, namely, “a similarity of religion.” By this conduct, Jai Singh is said emphatically, by his own countrymen, to have given the key of Hindustan to the Southron. The influence his character obtained, however, with the Mahrattas was even useful to his sovereign, for by it he retarded their excesses, which at length reached the capital. In a few years more (A.D. 1739), Nadir Shah’s invasion took place, and the Rajputs, wisely alive to their own interests, remained aloof from a cause which neither valour nor wisdom could longer serve. They respected the emperor, but the system of government had long alienated these gallant supporters of the throne. We may exemplify the trials to which Rajput fidelity was exposed, by one of “the hundred and nine deeds of Jai Singh” which will at the same time serve further to illustrate the position, that half the political and moral evils which have vexed the royal houses of Rajputana, take their rise from polygamy.
