text: The lost-wax method is well documented in ancient Indian literary sources. The Shilpa Shastras, a text from the Gupta Period (–550 AD), contains detailed information about casting images in metal. The 5th-century AD Vishnusamhita, an appendix to the Vishnu Purana, refers directly to the modeling of wax for making metal objects in chapter XIV: "if an image is to be made of metal, it must first be made of wax." Chapter 68 of the ancient Sanskrit text Mānasāra Silpa details casting idols in wax and is entitled Maduchchhista Vidhānam, or the "lost wax method". The 12th century text Mānasollāsa, allegedly written by King Someshvara III of the Western Chalukya Empire, also provides detail about lost-wax and other casting processes.
  In a 16th-century treatise, the Uttarabhaga of the Śilparatna written by Srïkumāra, verses 32 to 52 of Chapter 2 ("Linga Lakshanam"), give detailed instructions on making a hollow casting.
