Chemistry was another science that developed along with the medicine that helped in the development of metallurgy.
Nagarjuna the great Mahayanist was also genus in chemistry.
The Mehrauli iron pillar is a living memorial of this period. It portrays the progress in metallurgy achieved 1,500 years ago by the Indians. It has been surviving without rusting since its establishment (i.e. for over 1,500 years).
The economic prosperity of the country during the Gupta period led to all round development in the field of sculptural art, architecture, and painting.
In the Deccan, rock-cut caves were excavated. There are nine caves at Udaygiri near Vidisa. These are partly rock-cut and partly stone-built.
Ajanta caves were built on the new line of architecture by the great beauty of their pillars of varied design and size and the fine paintings with which the inner wall and ceiling are decorated.
Ellora’s rock-cut monasteries and chaitya halls are other piece of architecture. The Brahmanical, Buddhist, and Jain caves portray the final phase of development.
