Guicciardini was the contemporary and intimate friend of Machiavelli, but their several careers bore small similitude; for worldly prosperity attended the first, while the other was depressed by neglect and penury; and while his intellect struggled with these chains, the nobler parts of his disposition yielded to them. Machiavelli was a republican in principle, of humble for tunes, and dependent on his friends for their favour and encouragement. Guicciardini was a courtier; he was the servant of a prince, not of a state; in birth and position in life he had the advantage of his friend; and these combining circumstances rendered him more confident in himself, while at the same time it inspired him with an avowed dislike for popular governments.
The Guicciardini formed one of the noblest families of Florence: it was of ancient origin, and possessed several magnificent mansions in Florence. One of the streets is named de' Guicciardini, from containing a palace belonging to them; and they had large possessions in the Val di Pesa.
Francesco, the subject of this memoir, was the son of Piero de' Guicciardini, a celebrated advocate, and at one time commissary-general to the Florentine army. Francesco was one of eight children. His mother was Simona, daughter of the cavaliere Bongiani Gianfigliazzi, a noble Florentine. He was born on the 6th of March, 1482.[32] He was educated with care by the best masters, and taught Greek and Latin. He applied himself, as he grew up, to the study of logic and of civil law, as he was destined for the robe. He was sent to Ferrara by his father, not merely for the sake of attending the teachers there, but that his parent might have a place of refuge, where to send his property, in the event of civil disturbance or external attack upon Florence. Large sums of money were remitted to him, and he boasts of the trustworthiness of his conduct on this occasion, despite his extreme youth. It was in agitation at one time to make him a priest, as, through the interest of an uncle, who was rich in benefices, a prosperous career was opened to him in the church. He was himself inclined towards the clerical profession, as one full of honour and dignity; but his father decided against it, and resolved that none of his five sons should enter the priesthood; partly induced by the notion that the papal power was on the decline, and partly from a conscientious feeling of the impropriety of adopting the sacred calling, merely for the sake of temporal advantages. Instead, therefore, of assuming the sacerdotal garb, Francesco took a doctor's degree in law, and at an early age was appointed by the government to read the Institute in the university of Florence. He married the following year. His wife was Maria, daughter of Alamanno di Averardo Salviati, one of the first men of the city. Several law offices were bestowed on him, and he prides himself at this success in early life. But he felt himself still more honoured, when he was sent by the republic as ambassador to Ferdinand, king of Aragon. Italy was then the arena on which the adverse powers of France, Germany, and Spain contended for mastery. Florence adhered to the French party, but the timid gonfaloniere Soderini, desirous of currying favour on all sides, thought it right to preserve a good understanding with Ferdinand. Francesco, feeling his inexperience, shrunk from the responsibility of this mission, and did not accept it, till his father added his commands to those of the state.
