[1] Giovanni di Bardo Corsi was also a Renaissance humanist who actively participated in the rediscovery of classical language and literatures and the educational programme of the studia humanitatis.
[5] If Giovanni's fame appears above all linked to having occupied important public offices after the return of the Medici to Florence in 1512, it is also true that the first manifestations of its political tendencies begin to reveal themselves since the early 16th century.
In the subsequent period of the Orti Oricellari's flourishing between 1513 and 1522, when they became the center of the republican opposition, Giovanni would gradually move away, remaining consistent with its aristocratic ideals of restricted government.
[5] Giovanni had personally met Pontano during a trip to Naples between 1501 and 1503 and from him he had obtained a copy of the De prudentia, perhaps to spread its content in the circle of Florentine writers.
By that time, after the return of the Medici in 1512, with the numerous public offices held, Giovanni's humanistic commitment would have represented a marginal aspect of his activity.
The position of officer of Honesty, which he had occupied in 1498, that is, in the period following the expulsion of the Medici, certainly did not constitute a stain in the political past of Giovanni, who had always remained fiercely in opposition during the years of Soderini.
Precisely in 1512 he was elected a member of the nurse, the body that concentrated the legislative power and a large part of the executive, and in which the major aristocratic families were represented.
[5] The Medici government, in this, as in other cases, by entrusting Giovanni with a diplomatic post, knew how to put to good use the oratorical skills of a man of letters who by his contemporaries was often "heard to argue ornately in the public railings, about the integrity of life, of justice, of the Republic, of liberty, and of those praiseworthy offices which are owed to the charity of the fatherland".
[clarification needed] Between 1517 and 1522 he occupied the posts of captain in Pistoia (1517), was elected among the Conservatores legum (1518), was consul of the Sea in Pisa (1518), was among the Boni viri stincarum (1520), and among the eight guard (1520).
[5] This diplomatic mission, when Charles V extended his influence in Italy despite the opposition of Clement VII and defeating the French army in Pavia, immediately appeared more complex than the others carried out by Giovanni in Spain.
In a letter dated March 27, he set out the difficulties encountered: "Truly, after the capitulation made by His Holiness with the King Christianissimo, I had a very bad time negotiating in this court; and although I delayed and justified with giving those reasons that I they seemed to be the best in excusation of our Lord and ours, nevertheless it did not help".
As when, for example, the emperor, referring to the victory of Pavia, tacitly criticized the attitude of the former allies, arguing that "although this happiness might have seemed to him all the greater, as in it he had not had in the company of any of his friends, nevertheless he wanted it to be common to all".
The judgment according to which the few corrections made to the friend's manuscript can be considered "the greatest title of the literary fame of Corsi", as was claimed by Roberto Ridolfi, appears doubtful and ends up diminishing all the activity of a man of culture carried out by Giovanni in the first decade of the XVI century.
They are of greater interest in the reconstruction of the biographical events of Giovanni as they allow to highlight his humanistic commitment, which could appear limited to the period of his youth, and which on the contrary constitutes a constant aspect in his entire activity.
Giovanni expressed some general suggestions at the end of the reading, recognizing Guicciardini as the greatest historian: "Omnes procul dubio quotquot historiam scripserunt longe superas".
