From the Museum's website: With the help of his army of monkeys, Rama's invasion of Lanka is successful. Rama and his brother Lakshmana are depicted seated under a tree at left, as monkeys bring captured demons to them. The palace of the demon-king Ravana stands on the hill at top right in this illustration from the "Ramayana."
