CHIETI, a city of the Abruzzi, Italy, the capital of the province of
Chieti, and the seat of an archbishop, 140 m. E.N.E. of Rome by rail,
and 9 m. W. of Castellammare Adriatico. Pop. (1901) 26,368. It is
situated at a height of 1083 ft. above sea-level, 3 m. from the railway
station, from which it is reached by an electric tramway. It commands a
splendid view of the Apennines on every side except the east, where the
Adriatic is seen. It is an active modern town, upon the site of the
ancient _Teate Marrucinorum_ (q.v.), with woollen and cotton
manufactories and other smaller industries. The origin of the see of
Chieti dates from the 4th century, S. Justinus being the first bishop.
The cathedral has been spoilt by restoration, and the decoration of the
exterior is incomplete; the Gothic campanile of 1335 is, however, fine.
The cathedral possesses two illuminated missals. Close by is the town
hall, which contains a small picture gallery, in which, in 1905, was
held an important exhibition of ancient Abruzzese art. The de Laurentiis
family possesses a private collection of some importance. To the north
of Chieti is the octagonal church of S. Maria del Tricaglio, erected in
1317, which is said (without reason) to stand upon the site of a temple
of Diana. The order of the Theatines, founded in 1524, takes its name
from the city. Under the Lombards Chieti formed part of the duchy of
Benevento; it was destroyed by Pippin in 801, but was soon rebuilt and
became the seat of a count. The Normans made it the capital of the
Abruzzi.

CHI-FU, CHEFOO, or YEN-T'AI (as it is called by the natives), a seaport
of northern China, on the southern coast of the Gulf of Chih-li, in the
province of Shan-tung, near the mouth of the Yi-ho, about 30 m. E. of
the city of Teng-chow-fu. It was formerly quite a small place, and had
only the rank of an unwalled village; but it was chosen as the port of
Teng-chow, opened to foreign trade in 1858 by the treaty of Tientsin,
and it is now the residence of a Tao-t'ai, or intendant of circuit, the
centre of a gradually increasing commerce, and the seat of a British
consulate, a Chinese custom-house, and a considerable foreign
settlement. The native
