The conditions of enquiry
planned by Nicholas V, who had worked on the establishment of the San
Marco
library, it received its
official
form
under
Sixtus IV in
1475,
at which
time it contained 2,527 manuscript volumes. Scholars and ecclesiastics in
Rome could read and borrow manuscripts from the collection. One
element which distinguished the Vatican from other contemporary
libraries was its relatively large number of Greek manuscripts and recent
translations of philosophical and patristic works from Greek into Latin.
Valuable
also for Greek works was the library
of
Cardinal Bessarion, which
was
housed in Rome during his lifetime and
then
bequeathed to
Venice,
where it formed, after decades
of
neglect,
the basis
of
the Marciana Library.
Outside Italy
there
were collections such as those of the
King
of Hungary,
Matthias Corvinus (1440—90), which was built on the Italian model, of
the Englishman Humfrey, Duke of Gloucester, which included a wide
variety of manuscripts, and of the Duke of Burgundy, whose large library
reflected his medieval tastes. These libraries remained manuscript
collec-
tions
well
after the invention
of
printing. In fact, Federigo da Montefeltro,
Duke
of Urbino (1444-82), specifically eschewed
printed
books when
founding his large personal library. Many libraries housed more manu-
scripts
than
printed
books
well
into the sixteenth century.
A
different type of library, but one which had some importance in the
diffusion
of philosophical texts in the Renaissance, was
that
of individual
scholars. University
students
and professors often formed collections of
texts for their own specialised use, often maintaining catalogues with
apposite comments on the whole collection. Individuals also made their
own
collections of excerpts, called florilegia, from philosophical authori-
ties,
thereby bringing together from many manuscripts the material they
felt
important
to their research. These libraries are especially difficult to
judge since they were often dispersed after the death
of
their owners and the
extant catalogues are often incomplete.
Further,
we have no way of
knowing
how many scholars would have had access to these collections.
The
library of Giovanni Pico della Mirandola, which included a large
number of philosophical texts, ancient and medieval, was sold to his
nephew, Gianfrancesco
Pico,
but was dispersed after his death. Later
there
were the exceptionally large and varied collections
of
Fulvio
Orsini
(1529—
1600) in Rome and Gian Vincenzo Pinelli
(1535-1601)
in Padua. These
manuscripts subsequently entered other collections. The library
of
Giorgio
Valla
in Venice was especially rich in Greek scientific treatises and during its
owner's lifetime was open to scholars interested in mathematics. After
Valla's
death the books were dispersed. Whatever the limits of our
