On the 9th of July 1504, Wednesday, at seven o'clock, died Ser Piero
da Vinci, notary at the Palazzo del Podesta, my father, --at seven
o'clock, being eighty years old, leaving behind ten sons and two
daughters.

[Footnote: This statement of Ser Piero's age contradicts that of the
_Riassunto della portata di Antonio da Vinci_ (Leonardo's
grandfather), who speaks of Ser Piero as being thirty years old in
1457; and that of the _Riassunto della portata di Ser Piero e
Francesco_, sons of Antonia da Vinci, where Ser Piero is mentioned
as being forty in 1469. These documents were published by G.
UZIELLI, _Ricerche intorno a L. da Vinci, Firenze_, 1872, pp. 144
and 146. Leonardo was, as is well known, a natural son. His mother
'La Catarina' was married in 1457 to Acchattabriga di Piero del
Vaccha da Vinci. She died in 1519. Leonardo never mentions her in
the Manuscripts. In the year of Leonardo's birth Ser Piero married
Albiera di Giovanni Amadoci, and after her death at the age of
thirty eight he again married, Francesca, daughter of Ser Giovanni
Lanfredi, then only fifteen. Their children were Leonardo's
halfbrothers, Antonio (b. 1476), Ser Giuliano (b. 1479), Lorenzo (b.
1484), a girl, Violante (b. 1485), and another boy Domenico (b.
1486); Domenico's descendants still exist as a family. Ser Piero
married for the third time Lucrezia di Guglielmo Cortigiani by whom
he had six children: Margherita (b. 1491), Benedetto (b. 1492),
Pandolfo (b. 1494), Guglielmo (b. 1496), Bartolommeo (b. 1497), and
Giovanni) date of birth unknown). Pierino da Vinci the sculptor
(about 1520-1554) was the son of Bartolommeo, the fifth of these
children. The dates of their deaths are not known, but we may infer
from the above passage that they were all still living in 1505.]
