 The Sanskrit drama of Śakuntalā, as written by Kālidāsa, is also a parallel.A king had fallen in love with Śakuntalā, whom he married and gifted an emerald ring, with his name engraved upon it.However, when he returned to his capital, he forgot about Śakuntalā until one day a fisherman was seen selling such a ring in the marketplace and had been arrested.
