Satyrane (3 syl.).
A blunt but noble knight who delivered Una from the fauns and satyrs. The meaning is this: Truth, being driven from the towns and cities, took refuge in caves and dens, where for a time it lay concealed. At length Sir Satyrane (Luther) rescues Una from bondage; but no sooner is this the case than she falls in with Archimago, to show how very difficult it was at the Reformation to separate Truth from Error. (Spenser: Faërie Queene, bk. i.)
