It is said that King Arthur is not dead, but is only changed into a raven, and will in due time resume his proper form and rule over his people gloriously.

The raven was white till it turned tell-tale, and informed Apollo of the faithlessness of Corōnis. Apollo shot the nymph for her infidelity, but changed the plumage of the raven into inky blackness for his officious prating.--Ovid, Metamorphoses, ii.

He [Apollo] blackened the raven o’er,

And bid him prate in his white plumes no more.

Addison’s Translation of Ovid, ii.

If ravens gape against the sun, heat will follow; but if they busy themselves in preening or washing, there will be rain.

Rem´ora. A fish called the remora can arrest a ship in full sail.

A little fish that men call remora,

Which stopped her course ...

That wind nor tide could move her.
