ieces: 1. _De regia Sancti Lamentii
Bibliotheca_: 2. _De Bibliothecis_ (_Ex Fulvio Ursino_,) et
_De Bibliotheca Vaticana (ex Omphrii Schedis)_: 3. _De
Expurgandis haereticorum propriis nominibus_: 4. _De
Dipthycis_. Of these, the first, in which he treats of
collecting all manner of useful books, and having able
librarians, and in which he strongly exhorts Philip II. to
put the Escurial library into good order, is the most
valuable to the bibliographer. Vogt, p. 224, gives us two
authorities to shew the rarity of this book; and Baillet
refers us to the _Bibliotheca Hispana_ of Antonio.]

[Footnote 107: MUTIUS PANZA'S work, under the title of
_Ragionamenti della Libraria Vaticana_, Rome, 1590, 4to.,
and ANGELUS ROCCHA'S, that of _Bibliotheca Apostolica
Vaticana, Rome_, 1591, 4to., relate rather to the ornaments
of architecture and painting, than to a useful and critical
analysis, or a numbered catalogue, of the books within the
Vatican library. The authors of both are accused by Morhof
of introducing quite extraneous and uninteresting matter.
Roccha's book, however, is worth possessing, as it is
frequently quoted by bibliographers. How far it may be
"Liber valde quidem rarus," as Vogt intimates, I will not
pretend to determine. It has a plate of the Vatican Library,
and another of St. Peter's Cathedral. The reader may
consult, also, the _Jugemens des Savans_, vol. ii., p. 141.
My copy of this work, purchased at the sale of Dr. Heath's
books, has a few pasted printed slips in the margins--some
of them sufficiently curious.]

[Footnote 108: Consult Renouard's _L'Imprimerie des Alde_,
vol. ii., 122, &c. One of the grandest works which ever
issued from the Vatican press, under the superintendence of
Aldus, was the vulgate bible of Pope Sixtus V., 1590, fol.,
the copies of which, upon LARGE PAPER, are sufficiently well
known and coveted. A very pleasing and satisfactory account
of this publication will be found in the _Horae Biblicae_ of
Mr. Charles Butler, a gentleman who has long and justly
maintained the rare character of a profound lawyer, an
elegant scholar, and a well-versed antiquary and
philologist.]

Let us here not forget that the celebrated LIPSIUS condescended to
direct his talents to the subject of libraries; and his ver
