[1] The son of Giovanni Donà and Isabetta Morosini, Donato was born in Venice and studied for a time in Padua before going into trade.
He never married, and ultimately left his fortune to his brother Francesco and nephew Pietro.
Donato proved unwilling to spend the vast sums of money required to gain high office in the Republic of Venice.
In the midst of this crisis, the reigning Doge, Giovanni Bembo, died on 16 March 1618.
He tried to eliminate his reputation for stinginess by throwing the traditional lavish banquet to celebrate his election, but this proved unavailing when his parents turned a number of his relatives away from the feast in order to save money.
