Perhaps the most popular deity in the Hindu pantheon is the blue-skinned Lord Krishna, the eighth avatar or incarnation of Vishnu, preserver and protector of the universe. The tenth book of the Bhagavatapurana relates stories of Krishna’s childhood and youth. Scrolls like this with an impressive length of 21 metres were usually rolled up in a capsule made of metal, often attached to bands and worn on the upper arm or around the neck.
