Question for Apr 26 - PS

X was a philosopher, playwright, diplomat, musician, and civil servant, and is considered one of the main founders of modern political science. Like Leonardo da Vinci, X is considered a good example of the Renaissance Man. Since the sixteenth century, generations of politicians remain attracted and repelled by the cynical approach to power posited in his works. Whatever his personal intentions, which are still debated today, his surname yielded the modern political word Y — the use of cunning and deceitful tactics in politics.
