The early years Very little is known of Nardi's early life. Indeed, until recently his date and place of baptism (November 8, 1598 at
Santa Maria della Pieve in
Arezzo) were uncertain. His parents, Lazzaro Nardi and Caterina Tondinelli, were of minor provincial nobility originating from
Florence. Nardi received his degree in
utroque iure at the
University of Pisa in 1621. It was there that he likely came into contact with Galileans like
Benedetto Castelli, who held a chair in mathematics at
Pisa and was a longtime friend and supporter of Galileo.
The Rome years In the 1630s, Nardi became active in a group of
Castelli's students in
Rome that included
Evangelista Torricelli,
Michelangelo Ricci, and
Raffaello Magiotti. Nardi, along with Torricelli and Magiotti, wrote a number of letters to Galileo praising his
Dialogue Concerning the Two Chief World Systems and faulting its detractors after its publication in 1632. Galileo, recognizing their devotion, referred to the three as his "triumvirate" in Rome. In 1635, Nardi's uncle, Baldassarre Nardi secured him a position in the court of Cardinal
Giovanni Francesco Guidi di Bagno in Rome, which was home to many intellectuals like the Cardinal's librarian,
Gabriel Naudé. Nardi served there until the Cardinal's death in 1641. Around this time, Nardi renewed his correspondence with Galileo, sending him this time samples of his own geometrical work. These were from Nardi's
Ricercate Geometriche sopra Archimede, which is made up of newer, more efficient proofs of
Archimedes' original theorems using the new
method of indivisibles developed by
Bonaventura Cavalieri. Galileo's responses are not extant, but Nardi's subsequent letters indicate that Galileo approved of his work and that Nardi was even considering publishing it. This plan appears, however, to have fallen through when Galileo died in 1642 shortly after the death of Nardi's other patron, Cardinal di Bagno.
From 1642 to Nardi's death From 1642 onwards, there is little information on Nardi's activities. Although none of his own letters survive, the correspondence of Torricelli, Ricci, and
Marin Mersenne mentions Nardi frequently. During this time, he began composing his
Scene, of which the most complete and polished version is preserved as Gal. Ms. 130 in the
Biblioteca Nazionale Centrale in Florence. Ricci was working on having the manuscript published, as he contributed to the
Scene with some of his own mathematical work, but this never came to fruition. Nothing is known of when and where Nardi died. After the deaths of
Bonaventura Cavalieri and Torricelli in a
typhus outbreak in 1647, there is no trace of him in the Galileans' correspondence. It is likely that he too was killed by typhus. ==
