is mother and his next brother Giovanni, August 7, 1473,
in relinquishing all claims to the house in Genoa sold by his
father Domenico by deed of that date. It will be remembered
that Domenico had moved from Genoa to Savona in 1471. From
these documents (which are all printed in his _Christophe
Colomb_, tom. ii. pp. 419, 420, 424-426) M. Harrisse concludes
that Christopher cannot have gone to Portugal until after
August 7, 1473. Probably not, so far as to be domiciled there;
but inasmuch as he had long been a sailor, why should he not
have been in Portugal, or upon the African coast in a
Portuguese ship, in 1470 and 1471, and nevertheless have been
with his parents in Savona in 1472 and part of 1473? His own
statement "fourteen years" is not to be set aside on such
slight grounds as this. Furthermore, from the fact that
Bartholomew's name is not signed to the deed of August 7, 1473,
M. Harrisse infers that he was then a minor; i. e. under five
and twenty. But it seems to me more likely that Bartholomew was
already domiciled at Lisbon, since we are expressly told by two
good contemporary authorities--both of them Genoese writers
withal--that he moved to Lisbon and began making maps there at
an earlier date than Christopher. See Antonio Gallo, _De
navigatione Columbi per inaccessum antea Oceanum
Commentariolus_, apud Muratori, tom. xxiii. col. 301-304;
Giustiniani, _Psalterium_, Milan, 1516 (annotation to Psalm
xix.); Harrisse, _Bibliotheca Americana Vetustissima_, No. 88.
To these statements M. Harrisse objects that he finds (in
Belloro, _Notizie_, p. 8) mention of a document dated Savona,
June 16, 1480, in which Domenico Colombo gives a power of
attorney to his son Bartholomew to act for him in some matter.
The document itself, however, is not forthcoming, and the
notice cited by M. Harrisse really affords no ground for the
assumption that Bartholomew was in 1480 domiciled at Savona or
at Genoa.]
