Final answer:
Petrarch admired Cicero for his contributions to morality, writing, and the introduction of Hellenistic philosophy to Rome, which was consistent with the humanist ideals emphasizing human dignity and classical wisdom.
Step-by-step explanation:
Petrarch, considered the father of humanism, deeply admired Cicero for his writings, especially on topics such as morality. Cicero, a master of Latin prose with a substantial body of work that shaped Latin style and grammar, introduced Hellenistic philosophy to Rome and greatly influenced moral philosophy during the Middle Ages. His works were rediscovered in the 15th century, igniting the European Renaissance. Petrarch's appreciation of Cicero was in line with humanist ideals that emphasized the beauty and dignity of humanity, drawing wisdom from the classical worlds of ancient Greece and Rome, rather than focusing solely on divine study.
Cicero himself was held to high esteem for his public speaking skills and philosophical works, both of which played crucial roles in the Roman society. These skills, along with his contributions to politics as a consul of Rome, are what led European leaders and philosophers to look up to Cicero as a figure embodying the principles of leadership and moral integrity.
