Bold.

And as she lookt about, she did behold

How over that same dore was likewise writ,

Be bold, be bold, and every where Be bold,

That much she muz'd, yet could not construe it

By any ridling skill, or commune wit.

At last she spyde at that roomes upper end,

Another yron dore, on which was writ,

Be not too bold; whereto though she did bend

Her earnest mind, yet wist not what it might intend.

Edmund Spenser, from The Faerie Queen
