LAUN or CASSIB'ELAN (probably "Caswallon"), brother and
successor of Lud. He was king of Britain when Julius Caesar invaded
the island. Geoffrey of Monmouth says, in his _British History_, that
Cassibellaun routed Caesar, and drove him back to Gaul (bk. iv. 3, 5).
In Caesar's second invasion, the British again vanquished him (ch. 7),
and "sacrificed to their gods as a thank-offering 40,000 cows,
100,000 sheep, 30,000 wild beasts, and fowls without number" (ch. 8).
Androg'eus (4 _syl_.) "duke of Trinovantum," with 5000 men, having
joined the Roman forces, Cassibellaun was worsted, and agreed "to pay
3000 pounds of silver yearly in tribute to Rome." Seven years after
this Cassibellaun died and was buried at York.

In Shakespeare's _Cymbeline_ the name is called "Cassibelan."

[Illustration] Polyaenus of Macedon tells us that Caesar had a huge
elephant armed with scales of iron, with a tower on its back,
filled with archers and slingers. When this beast entered the sea,
Cassivelaunus and the Britons, who had never seen an elephant, were
terrified, and their horses fled in affright, so that the Romans were
able to land without molestation.--Drayton, _Polyolbion_, viii.

There the hive of Roman liars worship a gluttonous emperor-idiot.
Such is Rome ... hear it, spirit of Cassivelaun.

Tennyson, _Boadicea_.

of Candy_ (1647).

CASSIM, brother of Ali Baba, a Persian. He married an heiress and soon
became one of the richest merchants of the place. When he discovered
that his brother had made himself rich by hoards from the robbers'
cave, Cassim took ten mules charged with panniers to carry away part
of the same booty. "Open Sesame!" he cried, and the door opened. He
filled his sacks, but forgot the magic word. "Open Barley!" he cried,
but the door remained closed. Presently the robber band returned, and
cut him down with their sabres. They then hacked the carcass into four
parts, placed them near the door, and left the cave. Ali Baba carried
off the body and had it decently interred.--_Arabian Nights_ ("Ali
Baba, or the Forty Thieves").

CAS'SIO (_Michael_), a Florentine, lieutenant in the Venetian army
under the command of Othello. Simple minded but not strong-minded, and
therefore easily led by others who possessed greater power of will.
Being overcome with wine, he engaged in a street-brawl, for which he
was suspended by Othello, but Desdemo
