1895.

[358] The desk bearing a single volume shewn on this seat (fig. 93) is
modern.

[359] These measurements were taken by myself with a tape, in April 1898,
and verified in April 1899.

[360] This catalogue is in the State Archives at Modena.

[361] I visited Monte Oliveto 19 April, 1899.

[362] See _Ueber Mittelalterliche Bibliotheken_, v. T. Gottlieb. 8vo.
1890, p. 181. I have twice visited Assisi and examined the Catalogue here
referred to. My best thanks are due to Professor Alessandri for giving me
every assistance in my researches.

[363] Inprimis facimus inventarium de libris in libraria publica ad bancos
cathenatis in hunc modum. Et nota, quod omnia folia omnium librorum, qui
sunt in isto inuentario sive per sexternos vel quinternos aut quaternos
seu quemvis per alium numerum majorem vel minorem omnes quotquot sunt,
nomina quaternorum tenent, ut apparet in quolibet libro in primo quaterno
in margine inferiori; quare omnes sunt ante et retro de nigro et rubeo per
talem figuram intus cum suo numero signati. Item lictere alphabeti, qui
desuper postes ponuntur, omnes debent esse aliquantulum grosse et
totaliter nigre, sicut inferius in fine cuiuslibet libri signatur. The
spots round this figure are alternately black and red.

[364] Ducange s. v. _solarium_ shews that occasionally it =_armarium_.

[365] I have to thank Father C. J. Ehrle, _S. J._, Prefect of the Vatican
Library, for the very great kindness with which he has assisted me in
these researches during three visits to Rome in 1898, 1899, 1900; and also
the officials who allowed me to examine parts of the palace not usually
accessible to strangers.

Further, I wish it to be clearly and distinctly understood that my
researches are based upon an essay by M. Paul Fabre, _La Vaticane de Sixte
IV._, which had appeared in the _Milanges d'Archeologie et d'Histoire of
the Ecole Francaise de Rome_ for December 1895, but of the existence of
which I had never heard until Father Ehrle shewed it to me. On reading it,
I found that M. Fabre had completely anticipated me; he had done exactly
what I had come to Rome to do, and in such a masterly fashion that I could
not hope to improve upon his work. After some consideration I determined
to verify his conclusions by carefully examining the locality, and to make
a fresh ground-plan of it for my own use. I have also studied the
authorities quoted by M. Eugene Muentz (_Les Arts a la Cour des Pape
