Collection of 129 autograph letters of the Prince Ferdinando III of Tuscany, son of Cosimo III de' Medici, written between
1689 and 1713 to Lodovico Fantoni, diplomat and statesman and to Anton Francesco Montauti, special envoy from Tuscany to the
imperial court in Vienna, and one letter from Lodovico Fantoni, written in 1723, about the death of Cosimo III. Most letters
contain brief exchanges of information about everyday activities between the Prince, who spent most of his time in Florence
or Pisa, and Fantoni, who lived in Vienna, Madrid, Paris and, eventually, Venice. The letters usually deal with the events
the Prince attended (banquets and dinners) and with other aspects of his daily routine. The Prince also comments very briefly
on various European sovereigns (including the Holy Roman Emperor Leopold I and his wife, Margaret Theresa, and Madame Ursins,
a lady of the Spanish court) and their lives. However, some of the names that appear in the passages are concealed in ciphers.
Throughout the collection there are also occasional hints to the unhappy marriage between Ferdinando and Violante of Bavaria
(simply referred to as wife in the letters), and to the affairs that the Prince had with various gentlemen, including a Venetian
man named Cecchini (f. 73r). There are also mentions of an ongoing friendship with Anton Francesco Montauti (first mentioned
on f. 73r). Bound at the end of the volume is also a letter (probably written in 1698) addressed to Montauti where Ferdinando
asks him to make sure that the stay of Lodovico Fantoni, who was going to spend some time at the Viennese court, is pleasant
and comfortable. Also bound at the end of the volume is a long, detailed account of the last moments of the life of Ferdinando,
who died in 1713, written to the sister of the Prince, Anna Maria Luisa de' Medici, referred to as the Elettrice Palatina.
The last document also contains a description of the succession problem that arose at the death of the Prince, as Ferdinando
III died without heirs.
