All correct, except for the date, which was 1687 [1]. It happened during a war between the Venetians and the Ottoman Turks (the Turks stored gunpowder in the building; the Venetians fired a mortar at it). The Venetians compounded the damage by their incompetent attempt to loot some sculptures from the west pediment; these fell to the ground and smashed to pieces.
