together fifty-three papers. The third series, also in
octavo, appeared (1876-81), in quarterly numbers,
each volume having twelve lithographic plates; the
papers numbered altogether fifty-one. The fourth
series, in octavo, appeared in yearly volumes (1882-
89), each volume having twelve lithographic plates;
the six volumes contain altogether forty-three papers.
The fifth series, in octavo, appeared annually (1889-
94), with zincotype plates and illustrations in the
text; the last number was issued in 1894 by Giuseppe
Gatti. The final volume of each series contained a
full index which De Rossi prepared with the greatest
care. (4) "Musaici delle chiese di Roma anteriori al
secolo XV" (Rome, 1872), an imperial folio consist-
ing of chromolithographic plates with a text in French
and Italian. The work closed with the twenty-fifth
number, issued after De Rossi's death. (5) "Codicum
latinorum bibliothecEe Vaticanae", vol. X, Pt. I, Nos.
7245-8066, Pt. II, Nos. 8067-8471; vol. XI, Nos.
8472-9019; vol. XII, Nos. 9020-9445; vol. XIII,
Nos. 9446-9849. The indexes to vols. XI, XII, XIII,
"Codicum lat. Vat." are: Pt. I, index of authors; Pt.
II, index of places, things, and persons. These
manuscript indexes are used as reference books in the
Vatican Library. (6) " Inscriptiones Urbis Romse
latinse. Collegerunt Gulielmus Henzen et Johannes
Baptista de Rossi. Ediderunt Eugenius Bormann et
Gulielmus Henzen" (Berlin, 1876 — ). This consti-
tutes the sixth volume of the "Corpus Inscriptionum
Latinarum consilio et auctoritate academise litter-
arum regije BorussicEe editura" (Berlin). The in-
vitation to De Rossi to act as one of the leading edi-
tors was given 22 January, 1854. (7) The five annual
reports (1854-58), concerning the preparatory work
for the above-mentioned "Corpus Inscriptionum",
which appeared in the monthly bulletins of the Royal
Academy of Science of Berlin. The other annual re-
ports have not been published; this is also the case
with De Rossi's synopses of the epigraphical manu-
scripts in the libraries of Italy, France, Germany,
Switzerland, and Austria. The last named summaries
are of the greatest importance. (8) "(Euvres com-
pletes de Bartolommeo Borghesi " (9 vols., Paris, 1862-
84). Napoleon III entrusted the task of collecting
and editing the works and letters of the celebrated
Borghesi to a committee of French, German, and
Italian scholars, among whom De Rossi may be said to
have been the most important and assiduous. (9) " Mar-
tyrologium Hieronyinianum", prepared and edited in
collaboration with Louis Duchesne in vol. I, Novem-
ber, of the Acta SS. (Brussels, 1894). This edition is
a masterpiece and most of the objections raised against
it by German scholars are of little importance.
The works briefly described above give some con- ception of the learned labours De Rossi carried on dur- ing his life They are proofs of the genius with which he grasped a subject, of his extraordinary industry, his learned mastery of the most varied subjects, and the unwavering determination with which he imeart.hed obscure points; they also show the triumphs with which his toils were so richly crowned. The estima- tion in which his work was held is proved by the two international celebrations in 1882 and 1892 upon his sixtieth and seventieth birthdays.
De Rossi's father died in 1850, and his mother in 1861. In the latter year he married Costanza, daughter of Count Pietro Bruno di San Giorgio Torna- fort of Piedmont, by whom he had two tlaughters; Marianna, the elder, died in 1864. The second, Na- talia, born in 1866, married the Marchese Filippo Fer- raioli. De Rossi's brother Mifhcl<' Sicfano was his zealous assistant in the exploratimi of the catacombs; the geological questions cotiiH'ctid with the.se subter- ranean places of burial and all kindred subjects are treated by Micheh; in separate papers in " Roma Sot- terranea". He also prepared the very accurate plans of the catacombs. De Rossi was a portly man of fine
appearance, somewhat over the middle height. The
full, well-proportioned face was surrounded by a
grayish beard which left the chin free. The clear, calm
eyes lost much of their strength, so that he could not
always supervise properly the work of his painters and
draughtsmen in the catacombs. This explains the
numerous inaccurate illustrations in his works which
Wilpert has corrected. The smoothly brushed hair
gave greater prominence to the high domed forehead.
In walking De Rossi bent slightly forward, which man-
nerism gave to his gait an appearance of much delib-
erateness. On the street he was generally busy with a
book or pamphlet. De Ro.ssi heard Mass every day
and went to Communion nearly every week. Gener-
ous, unobtrusive charity was a second nature with
him. Every evening he gathered all the members of
his household about him for the recitation of the ros-
ary. Although he very often received tempting offers
to desert the cause of the Holy See and join the party
of United Italy, he rejected all such proposals, even
when they came from the highest authorities. On
this point he was absolutely immovable. A few
months after the international celebration of his sev-
entieth birthday in 1892, De Rossi had an attack of
apoplexy from which he never entirely recovered.
Unable after this to use his right hand he continued to
write with the left for the "Bullettino" and in making
the corrections to the "Martyrologium". But his
days were numbered. In the summer of 1894 Leo
XIII offered him the use of an apartment in the papal
palace at Castel Gandolfo, where he peacefully passed
away, a true son of the Church. He was buried in the
Agro Verano (general cemetery) at Rome.
