ARCHEOLOGY. 273 



A last and unfinished piece of work was in connection with the 

 main city gate at Ostia. This triumphal gate, first built in the late 

 Republic, then refaced and redecorated under the Middle Empire on 

 a higher level, has been recently excavated and enough of its structure 

 and decoration found to make an ideal reconstruction possible. The 

 director of the excavations, Professor Dante Vaglieri, has requested 

 Professor Frothingham to direct this reconstruction, placing two of 

 his assistants at his disposal for this purpose.

During the fall and early winter of 1912-13 but little new work 

 was undertaken. The greater portion of the time, after the conclu- 

 sion of the International Congress of Archeology, which was held in 

 Rome in October, was given instead, (1) to the preparation of a 

 special bibliography for the various monuments, as well as to an 

 examination of the more important collections of early prints in 

 which the ancient buildings are represented; and (2) to the identifi- 

 cation and classification, by means of the data thus obtained, of the 

 more important monuments in the different regions w^hich are now 

 destroyed or inaccessible. The latter part of the year was devoted, 

 in large part, to the regular work on the methods of concrete con- 

 struction, with a view especially to the completion of the data 

 necessary for the publication, as soon as possible, of a fuller and more 

 exact canon or norm of construction. 



The discover}^, during the year, of a large number of new walls of 

 the time of Nero, in the vicinity of the Colosseum, as well as of the 

 more extensive remains under the so-called domus Augustana on the 

 Palatine, with the interesting study of the frescoes of the domus 

 Aurea made by De Weege, of the University of Bonn, has led to a 

 new and more general interest in the work of that period. The time 

 has seemed opportune, therefore, not only for the more thorough 

 study of the many remains of the period in other parts of the city, but 

 especially for the completion and publication, as soon as possible, of 

 the extensive plan, begun several years since, of the Neronian remains 

 on the Velia. 



With the kindly assistance of Dr. Thomas Ashby, Director of the 

 British School in Rome, whose exhaustive work on the aqueducts is 

 soon to appear, a special investigation has been begun of the problems, 

 both structural and chronological, presented by the Claudian and 

 the Marcian Aqueducts. As a result of this merely preliminary 

 examination, it has been possible not only to determine more defi- 

 nitely the extent of the various restorations already recognized, but 

 also to assign to the time of Hadrian extensive remains not before
