NOTE

 ¹Archive of the Primaziale of Pisa, Book of "baptised", signed C, char 36t. Reprinted in facsimile in the National Edition Opere di Galileo Galilei, Barbera, Florence 1968; XIX, p.25, this will be referred to as G.G. The volume is shown in Roman numbers.

 ²Deciphering the abbreviations, Antonio Favaro reads: "Galileo, of Vincentio Ghalilei of Florence and of his wife Lady Giulia was baptised in St Andrew Chapel on 19th in the presence of friends and cavaliers, Sir Pompeo and Sir Haverardo de' Medici ". See his paper: "Sulla Veridicita' del "Racconto Istorico della Vita di Galileo" Dictated by Vincenzio Viviani", Archivio Storico Italiano, 1915, 323-380.

 ³As is shown in Alcune Notizie intorno alla Vita del Galileo, Avute da Vincenzio Galilei, Figliuolo et Herede del Galileo, mentioned in G. G, XIX, 594-596.

 ⁴Even though Galileo's blessing, Ferdinand was dead a few days after, on the 7th February.

 ⁵In the second date, 6 is actually a correction of 5.

 ⁶Antonio Favaro, "In quel giorno del febbraio '64 dovrebbe celebrarsi la ricorrenza del natalizio del Galilei?". In Atti e Memorie della R. Accademia di scienze, lettere ed arti in Padova, 1908, vol. XXIV, 6-8: the author left the problem about the exact date to posterity. "If they want to establish the day for celebration at exactly four hundred years after the instant he opened his eyes for the first time".

 ⁹Galileo had never had the citizenship of Pisa, therefore, from a legal point of view, his father's provenance should be attributed to him as well.

 ¹²Therefore, it was 1563.

 ¹³The contract says: "domum unam solariatam tribus solariis, cum claustro, puteo et allis suis pertinentis, sitam Pisis in classo Mercatorum.
