CEPHEUS, in Greek mythology, the father of Andromeda (q.v.); in
astronomy, a constellation of the northern hemisphere, mentioned by
Eudoxus (4th century B.C.) and Aratus (3rd century B.C.). Ptolemy
catalogued 13 stars in this constellation, Tycho n, and Hevelius 51. The
most interesting star in it is [delta] _Cephei_, a remarkable double
star, the brighter component of which is a short period variable (5.37
days), with a range in magnitude of 3.7 to 4.9; it is also a
spectroscopic binary.

CEPHISODOTUS, the name of the father and of the son of Praxiteles, both
sculptors like himself. The former must have flourished about 400 B.C. A
noted work of his was Peace bearing the infant Wealth, of which a copy
exists at Munich. Peace is a Madonna-like figure of a somewhat
conservative type; the child Wealth is less successful. Cephisodotus
also made, like his son, a figure of Hermes carrying the child Dionysus,
unless indeed ancient critics have made two works of one. He made
certain statues for the city of Megalopolis, founded in 370 B.C. Of the
work of the younger Cephisodotus, his grandson, we have no remains; he
was a prolific sculptor of the latter part of the 4th century B.C.,
especially noted for portraits, of Menander, of the orator Lycurgus, and
others (see J. Overbeck, _Antike Schriftquellen_, p. 255).

CERAM (_Sirang_), an island of the Dutch East Indies, in the Molucca
group, lying about 3 Deg. S., and between 127 Deg. 45' and 131 Deg. E.
Its length is a little over 200 m., its greatest breadth about 50 m.,
and its area, including neighbouring islets, 6621 sq. m. It consists of
two parts, Great Ceram and Little Ceram or Huvamohel, united by the
isthmus of Taruno; and, for administrative purposes, is assigned to the
residency of Amboyna, being divided into Kairatu or West Cera
