English: Vastu sastras are treatises on architecture, arts and crafts. There are numerous such texts, but except for a few, most are lost to history or have only survived partially.

This is one side of a page from the Viswakarmaprakasa, a partial manuscript on Hindu architecture, estimated to be from the 17th-century. The language is Sanskrit, the script Devanagari. It was found in Kathmandu valley of Nepal. The text opens with prayers to Ganesha, then discusses the principles of site visit, soil testing, planning, design, layout, measurements, arrangement of spaces and geometry.

This particular page mentions puja (prayers with offerings) before the project, site visit and soil testing.

A copy of this text is preserved in the British Library, item EAP790/21/61.
