The Sulbasutras- Baudhayana, Apastamba, Katyayana and Manava with Text, English Translation and Commentary (Old and Rare book),In the last century, and at the beginning of the present, George Thibaut and A. Bark brought to the notice of the scholarly world the mathematical significance of two zina texts, namely the Sulba-strar by Baudhayana and Apastamba. These two works are manuals for the construction of various types of altars for fire-sacrifice, an ancient cult fully established in the time of the Samhits. Their mathematical importance lies in a precise statement of the squared relationship of the two sides and the diagonal of a rectangle, the realization of the irrationality of numbers like 2, efforts to determine their approximate values, formulation of rules for combining rectilinear figures, transforming squares into rectangles, triangles, trapeziums and circles and vice versa, the use of simple fractions and approximate values of. All these arose from the mensuration of laying altars of a fixed square area but of different shapes and filling them with a fixed number of bricks necessarily of different geometrical shapes. The Greek tradition of the development of geometry from the more ancient Egyptian mensuration, the rope- stretcher's art, appears to have its counterpart in the scriptural tradition of the halbtras. That similar tradition obtained in other culture areas has become increasingly clear with advancing knowledge of the cuneiform texts and ancient Chinese mathematical sources. I am happy that the authors of the present monograph have presented the full critical texts and translations of the four alba-stras by Baudhayana, Apastamba, Karyayana and Manava and modern commentaries on them. A carefully prepared introduction has dealt with: the genesis of these texts as part of the ritual literature (Kalpasatras) constituting one of the six Veddigar; the vexed question of the antiquity of these sitrar; the philosophical significance of performing fire sacrifices on various types of altars; and other reated questions. Regarding the dating of Baudhayana, Manava, Apastamba and others a balanced view has been maintained between the opinions of European sanskritists like Buhler, Keith, Macdonell, Renou and Filliozat and those of Indian scholars like Kane and Ramgopal. Though the date of Baudhayana, the earliest of sitra writers, still varies over a range of two to three centuries, there is no doubt that the tradition of altar construction and the related sacrifices goes back to the period of the Saphitts and the Brahmapas antedating the satras, as the numerous passages in the Taittiriya, Maitrayaai, and Kepijthala Samhitas and the Satapatha and other Brahmanas amply indicate.
