266 G. Thibaut — On the S'ulvasutras. [No. 3, 



Purusha means here not the ordinary purusha, but the measure of the 

 side of one of the fifteen squares into which the agni has been divided. The 

 form of the chiti is that of a trapezium (as the sutras would call it : an 

 oblong shorter on one side), the east side of which is equal to three reduced 

 purushas, &c. 



The area of this trapezium is consequently equal to 7-| square puru- 

 shas. 



This area has now to be divided into two hundred parts. 



With three of these parts construct an oblong of the breadth of one 

 part (an oblong of which one side is equal to three times the side of one of 

 the fifteen squares, and the other equal to one time the side), draw from the 

 middle of the east side of this oblong lines to the two west corners, and cut 

 off the two side pieces. 



After the removal of these two pieces, there remains a prauga, an acut- 

 angular equilateral triangle. 



This triangle is divided into ten parts. 



For the details of this division, we must consult the commentator :

The division of this triangle is to be made in such a way as to produce 

 bricks of the shape of triangles and double triangles (two triangles joined 

 with their bases). If we adopted another division, we should get different 

 classes of bricks. (The sutras always study the greatest shortness in their 

 expressions and say in this case only : the division is into ten parts. Now, 

 the commentator remarks, this can only mean : into ten triangles and 

 double triangles ; for if we divide the large triangle in any other manner, 

 the eight parts would be of different shape, and then the sutrakara would 

 have been bound to give rules for manufacturing bricks of these different 

 shapes). The division of the triangle is effected in the following manner. 

 "We make on the " broad face", i. e., the base of the triangle (the sutraka- 

 ras compare the triangle with a face, the base — we have to imagine the
