CASSIOPEIA, in Greek mythology, the wife of Cepheus, and mother of
Andromeda; 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 Brahe 46, and
Hevelius 37. Its most interesting stars are:--_Nova Cassiopeiae_, a
"new" star, which burst out with extraordinary brilliancy in 1572, when
it was observed by Tycho Brahe, but gradually diminished in brightness,
ultimately vanishing in about eighteen months; _[alpha]-Cassiopeiae_ and
_R-Cassiopeiae_ are variable stars, the former irregular, the latter
having a long period; _[eta]-Cassiopeiae_, a binary star, having
components of magnitudes 3-1/2 and 7-1/2; _[sigma]-Cassiopeiae_, a
double star, one being white and of magnitude 5, the other blue and of
magnitude 7-1/2.

CASSITERIDES (from the Gr. [Greek: kassiteros], tin, i.e.
"Tin-islands"), in ancient geography the name of islands regarded as
being situated somewhere near the west coasts of Europe. Herodotus (430
B.C.) had dimly heard of them. Later writers, Posidonius, Diodorus,
Strabo and others, call them smallis
