ANCIENT TEXTS ON ALCHEMY

ANCIENT TEXTS ON ALCHEMY

Introduction

In India, chemistry was practiced as an art to manufacture mercury, zinc, copper and their alloys as early as around 3000 BCE. Production of medicines and plant extracts to cure diseases was very well developed as aids to Ayurveda and other forms of Healthcare.

Similar to that of Paracelsus in Europe, the chief aim of chemistry in India was to provide relief to humans from ailments. There are treatises like those of Charaka and Sushruta dealing with chemistry, medicine and surgery in ancient times. Great attention was paid to carry out minute details of the formulae for the preparation of drugs such as extract of plants by leaching, decoction or distillation. Manufacture of various metal powders under specific conditions of temperatures and pressures. This systematic development of chemistry, coupled with some accidental discoveries, ultimately led to the development of ‘Kimaya’, the term used for alchemy (the infant stage of chemistry) in India.

Ancient Indian chemists were using more than 32 types of apparatus for chemical and pharmaceutical investigations in their laboratories and they are called ‘Yantras’, The Rasa-ratna-samuccaya talks of a variety of furnaces for melting and distillation. Of these 3 types of furnaces are dealt with here:

  • The Koshti-yantra
  • The Dhekhi-yantra and
  • The Tiryak-patana-yantra.

Etymology

Vahni-karmatii = Fire related activities = Melting

Rasa-bhairavah = King amongst chemicals = Mercury

Sulba-ariti = The enemy of metals = Sulphur

Notes

1.   Chemistry was a hand-maid of medicine. Hence, the need to locate a laboratory where medicinal plants are available.

2.   The poetic style used to indicate the 3 directions is quite interesting, full of alliteration. Yaksha (a particular class of divine-beings), Traksha (the 3-eyed-Shiva), and Sahasraksha (the 1000-eyed-Indra).

3.   The recommended layout for laboratories is in consonance with the Hindu thought on gods and their domain. Northwest is the direction of the god of wind and therefore drying should be located in the northwest. The recommended layout is tabulated below:

S.No Direction Direction Presiding Domain Recommended
  (in Sanskrit) (in English) deity of the lord activity    
1 Uttara North Kubera Wealth Piercing    
2 Uttara-poorva North-east Shiva Ownership Storage of ready
              to use goods.
3 Poorva East   Indra Chief of the Storage of the
          Devas king of chemicals.
4 Dakshina- South-east Agni Fire Heating/

Interesting facts

Indigo dyes of the Kurmis

While the Europeans used woad or isatis tinctoria, the Indian plant indigofera tinctoria or Nila, has a higher indigo content and the methodology used by the dyers in India is remarkably similar and efficient. The technology in our country was handed down from fathers to sons over centuries. In a nation full of castes and communities, each specializing in one art, craft or technology, it was the kurmis of Maratha and Deccan, the Niralis of Central India, and certain groups of Muslim dyers who have been exponents of this form of medieval biotechnology.

Exports without quota

Eighth century Central Asia and Egypt knew of Indian textiles. Marco Polo, who passed through India in the 13th century, was the first to report on the preparations of Indigo dye in India.

Block printed, resist – dyed textiles from Gujarat and the Deccan adorned Europeans and their homes from the 15th to the 19th centuries. Flourishing trade in textiles and dyes existed between the Golconda kingdom of Telangana and Qutub Shahi, Persia for centuries.
