Zaira is an Italian opera based on one of Voltaire's writings. It is about a Christian woman named Zaira. She falls in love with the Muslim Sultan of Jerusalem, Orosmane.
Zaira is a city in Italo Calvino's 'Invisible Cities', which is found in the section of 'cities and memory'. It is observed that a description of the city as it is 'today' should contain all of its history, which is written in every feature of the city, from the gratings of the windows to the lightning rods.
