Indian dhal, late 19th century
Indian dhals (shields) are typically round but can vary in diameter from 8 inches to 24 inches. This dhal is likely to have belonged to a child. The four bosses on the front support and secure the grip on the back.
Some shields are strongly convex or curved for extra reinforcement and to help deflect any lance head or arrow. Dhals were generally made from hide while others, like this one, were made from metal.
