The personal life of Leonardo da Vinci 15 April 1452 – 2 May 1519 has been a subject of interest, inquiry, and speculation since the years immediately following his death. Leonardo has long been regarded as the archetypal Renaissance man, described by the Renaissance biographer Giorgio Vasari as having qualities that "transcended nature" and being "marvellously endowed with beauty, grace and talent in abundance.'' Interest in and curiosity about Leonardo has continued unabated for five hundred years.Modern descriptions and analysis of Leonardo's character, personal desires and intimate behavior have been based upon various sources: records concerning him, his biographies, his own written journals, his paintings, his drawings, his associates, and commentaries that were made concerning him by contemporaries.
