Rialto comes from the name for the mercantile quarter of Venice during the middle ages. Shakespeare is thought to have brought the term into widespread usage from his play the Merchant of Venice, first performed at the turn of the seventeenth century. While it initially referred only to the specific marketplace in Venice, rialto soon took on a broader sense and could be applied marketplaces elsewhere.
