The Calcutta-born novelist Amitav Ghosh tells the tale, in his novel In an Ancient Land, of a medieval traveler by the name of Abraham Ben Yiju who conducted an import/export business from Cairo through Aden to India. Ben Yiju was a member of the Synagogue of Ben Ezra, or the”Synagogue of the Palestinians”, as it used to be known while it was still standing, in Cairo, at the end of the nineteenth century. It was in that synagogue that congregation members used to accumulate and store their papers and manuscripts. The last In an Ancient Land Revisited Trade and Synagogues in South India document that is known to have been deposited in this Genizah was a get, a divorce settlement, authorized in Bombay (today Mumbai).
