(r. 1492-1503) The memorably decadent Rodrigo Borgia (given name) was a financial supporter of Leonardo da Vinci. Perhaps the most corrupt of the Renaissance popes, Alexander VI became a cardinal at age twenty-nine and lived a notoriously licentious life, siring six or more illegitimate children (including Caesar Borgia, brutal commander of the papal army). Some believe he became pope by bribing the electors; as a pope who lived luxuriously, he also spent vast sums on building projects in Rome. See also Renaissance.
