entered the papal
chapel in 1660. In 1666 he became _Vice-Kapellmeister_ at Vienna, and
died at Venice in 1669. Cesti is known principally as a composer of
operas, the most celebrated of which were _La Dori_ (Venice, 1663) and
_Il Pomo d' oro_ (Vienna, 1668). He was also a composer of
chamber-cantatas, and his operas are notable for the pure and delicate
style of their airs, more suited to the chamber than to the stage.

CESTIUS, LUCIUS, surnamed Pius, Latin rhetorician, flourished during the
reign of Augustus. He was a native of Smyrna, a Greek by birth.
According to Jerome, he was teaching Latin at Rome in the year 13 B.C.
He must have been living after A.D. 9, since we are told that he taunted
the son of Quintilius Varus with his father's defeat in the Teutoburgian
forest (Seneca, _Controv._ i. 3, 10). Cestius was a man of great
ability, but vain, quarrelsome and sarcastic. Before he left Asia, he
was invited to dinner by Cicero's son, then governor of the province.
His host, being uncertain as to his identity, asked a slave who Cestius
was; and on receiving the answer, "he is the man who said your father
was illiterate," ordered him to be flogged (Seneca, _Suasoriae_, vii.
13). As an orator in the schools Cestius enjoyed a great reputation, and
was worshipped by his youthful pupils, one of whom imitated him so
slavishly that he was nicknamed "my monkey" by his teacher (Seneca,
_Controv._ ix. 3, 12). As a public orator, on the other hand, he was a
failure. Although a Greek, he always used Latin in his declamations,
and, although he was sometimes at a loss for Latin words, he never
suffered from lack of ideas. Numerous specimens of his declamations will
be found in the works of Seneca the rhetorician.

CESTUI, CESTUY, an Anglo-French word, meaning "that person," which
appears in the legal phrases _cestui que trust_, _use_, or _vie_. It is
usually pronounced as "cetty." _Cestui que trust_ means literally "the
person for whose benefit the trust" is created. The _cestui que trust_
is the person entitled to the equitable, as opposed to the legal,
estate. Thus, if land be granted unto, and to the use of A. in trust for
B., B. is _cestui que trust_, and A. tru
