COLLATIA, an ancient town of Latium, 10 m. E. by N. of Rome by the Via
Collatina. It appears in the legendary history of Rome as captured by
Tarquinius Priscus. Livy tells us it was taken from the Sabines, while
Virgil speaks of it as a Latin colony. In the time of Cicero it had lost
all importance; Strabo names it as a mere village, in private hands,
while for Pliny it was one of the lost cities of Latium. The site is
undoubtedly to be sought on the hill now occupied by the large medieval
fortified farmhouse of Lunghezza, immediately to the south of the Anio,
which occupies the site of the citadel joined by a narrow neck to the
tableland to the south-east on which the city stood: this is protected
by wide valleys on each side, and is isolated at the south-east end by a
deep narrow valley enlarged by cutting. No remains are to be seen, but
the site is admirably adapted for an ancient settlement. The road may be
traced leading to the south end of this tableland, being identical with
the modern road to Lunghezza for the middle part of its course only.
The current indentification with Castellaccio, 2 m. to the south-east,
is untenable.

COLLATION (Lat. _collatio_, from _conferre_, to bring together or
compare), the bringing together of things for the special purpose of
comparison, and thus, particularly, the critical examination of the
texts of documents or MSS. and the result of such comparison. The word
is also a term in printing and bookbinding for the register of the
"signatures," the number of quires and leaves in each quire of a book or
MS. In Roman and Scots law "collation" answers to the English law term
"hotch-pot" (q.v.). From another meaning of the Latin word, a
consultation or conference, and so a treatise or homily, comes the title
of a work of Johannes Cassianus (q.v.), the _Conferences of the Fathers_
(_Collationes Patrum_). Readings from this and similar works were
customary in monasteries; by the _regula_ of St Benedict it is ordered
that on rising from supper there should be read _collationes_, passages
from the lives of the Fathers and other ed
