A prince survives by unseen acts. br At night the chief advisor knocked br at Frederick's workroom in the tower br and found him formulating facts br for treatises on wingèd power br while his penman turned out text. br br It was in this aerie room br he'd walked all night with her on arm, br turbulent and barely fledged. br Whatever plans then sprang to mind, br whatever fondness deeply chimed br in recollection he would trash br and tend the frightened and impassioned br thing he wished to understand. br Every night he made a time br for nothing but the young unhandled br animal. It was her staring br inborn mind he'd worked to learn, br br so he was lofted with her grace br when she, the bird that nobles praise, br thrown gleaming from his hand (her wingbeats raised br into the heartfelt morning air) br and diving like an angel struck the hern.
