Rumal with Scenes from the Ramayana
embroidery, 18th century
From the Museum website:
At the upper right, Rama, Sita, and Lakshmana bid farewell to Rama's mother before their exile in the forest. The middle scene depicts Ravana, disguised as an ascetic, attempting to seduce Sita in the forest while her husband is hunting a golden deer sent by Ravana as a diversion. Sita is abducted by Ravana and next seen imprisoned in his palace on Lanka (lower left). Finally, Rama, Lakshmana, Hanuman, and the monkey and bear armies cross Nala's bridge to Lanka and advance on Ravana's fortress, slaying Ravana. Returning to the center of the embroidery, Rama, Sita, and Lakshmana depart in triumph, carried on palanquins.
