This is the story of the man who conquered and seduced the one who, immortalized indecipherably by Leonardo, with her gaze then seduced the world. It is the story of Tristan, a young pontifical diplomat with a mysterious and dark past who, among strategies and deceptions, between adventures and plots, between intrigues and the wars of Renaissance Italy, brilliantly carried out his missions, one after the other, using the art he knew best, the most powerful weapon: that of seduction. However, the moment came when fate commissioned him the most important undertaking ... A precariat researcher from the CNR of Pisa, an expert in cryptography and blockchain, accidentally finds a strange encrypted file in an archive of a Tuscan abbey that contains an incredible, extraordinary, unpublished story ... from which he can no longer detach himself. In a cold night in which History gave the general rehearsals of the Renaissance, while the lords of Italy annihilated each other for the ephemeral control of the fragile borders of their States, a young pontifical diplomat with a mysterious past preferred to try his hand at the art of seduction more than that of war. Who was he? He was no prince, leader, prelate, he had no official title ... yet talking to him was equivalent to conferring directly with the Holy Father, he moved casually on the complex political chessboard of that period but never left a trace, he wrote History every day but never appeared in any of its pages ... he was everywhere and yet it was as if he did not exist. From a lordship to another, from a kingdom to a republic, between strategies and deceptions, between adventures and plots, Tristan successfully completed his missions ... until fate commissioned him the most important undertaking: to discover who he really was. To do this he had to decipher a letter from his real mother, kept hidden for 42 years by the most powerful caste of the time. To do so, he had to go through that incredible temporal interstice with an extraordinary and unprecedented concentration of characters (statesmen, leaders, artists, writers, engineers, scientists, navigators, courtiers, etc.) and who significantly, drastically and irreversibly have changed the course of history. To do this he had to seduce the one who Leonardo had immortalized indecipherably, and with her gaze had seduced the world. Translator: Rosemary Dawn Allison PUBLISHER: TEKTIME
