Which of these title holders traditionally cast a ring into the sea in a ceremony representing the city’s marriage with the sea?

The Doge of Venice was the chief magistrate and ruler of the historic Venetian Republic. Venice traditionally celebrated its symbolic union with the sea through a ceremony known as the Marriage of the Sea (Sposalizio del Mare). During this ritual, the Doge cast a consecrated ring into the Adriatic Sea, symbolizing Venice\'s enduring relationship with the sea and its maritime power.

The ceremony reflected Venice\'s historical dependence on maritime trade, navigation, and naval strength. The ring represented the symbolic bond between the city and the waters that contributed to its prosperity.

Why the other options are incorrect:

• Mayor of Amsterdam: Amsterdam is famous for its canals and maritime trading history, but its mayor is not associated with this ceremony.
• Sultan of Istanbul: Istanbul has a rich maritime history, but its rulers did not traditionally perform Venice\'s Marriage of the Sea ritual.
• Governor of Mumbai: Mumbai is a major port city in India, but its governor is not associated with this Venetian tradition.
