बृहत्संहिता (आचार्य वराहमिहिर - स्थापत्य, खगोल, मौसम व जल विज्ञान)

Adh: LIII. Sl. 26-28.] त्रिपञ्चाशोऽध्यायः 429
added an eighth part of itself. That will give the width
of the door; and thrice this will be its height.
The width of Brahmin house is 32 cubits. ²⁴⁄₄ is 6. This is
to be taken as 6 digits. Add 18. i. e., 6+18 = 24 digits.
24+ ⅛ of 24 = 27 digits. This is its breadth and 27 × 3 = 81
digits, its height.
उच्छ्रायहस्तसंख्यापरिमाणान्यङ्गुलानि बाहुल्यम् ।
शाखाद्वयेऽपि कार्यं सार्धं तत् स्यादुदुम्बरयोः ॥२६॥
उच्छायात्सप्तगुणादशीतिभागः पृथुत्वमेतेषाम् ।
नवगुणितेऽशीत्यंशः स्तम्भस्य दशांशहीनोऽग्रे ॥२७॥
Slokas 26-27.—The thickness of the two side-frames
of the door is as many digits as the height numbers
cubits. One and a half times this gives the thickness of
the threshold and the upper-block. The breadth of all
the four pieces is an eightieth part of seven times the
door-height. An eightieth part of nine times the height
(of a storey) gives the width of a pillar at the bottom;
and the same lessened by a tenth is its width at the top.
A pillar of the ground floor in a King's house will
have a width of about 1 cubit and 5 digits at the bottom
and about 1 cubit and 2 digits at the top. Its circum-
ference is thrice the width.
समचतुरस्रो रुचको वज्रोऽष्टाश्रिर्द्विवज्रको द्विगुणः ।
द्वात्रिंशता तु मध्ये प्रलीनको वृत्त इति वृत्तः ॥२८॥
Sloka 28.—A pillar that is perfectly square in the
middle (leaving off the two ends) is called Ruchaka;
one that is octagonal, a Diamond; one with sixteen
angles (or sides), a double Diamond; one with 32 sides,
Praleenaka; and a round one is called a cylinder.
