To renew our youth, like the eagle’s, is an old scriptural expression (_Psalms_, ciii. 5); and various arc the legends and interpretations belonging to the phrase.[159] We must not wander among these,—but may mention one which is given by Joachim Camerarius, _Ex Volatilibus_ (Emb. 34), for which he quotes Gesner as authority, how in the solar rays, hawks or falcons, throwing off their old feathers, are accustomed to set right their defects, and so to renew their youth. RENOVATA IVVENTVS. [Illustration: _Camerarius, 1596._] _Exuviis vitii abjectis, decus indue recti, Ad ſolem ut plumas accipiter renovat._ [Sidenote: _i.e._] “Sin’s spoils cast off, man righteousness assumes, As in the sun the hawk renews its plumes.” The thought of the sun’s influence in renovating what is decayed is unintentionally advanced by the jealousy of Adriana in the _Comedy of Errors_ (act ii. sc. 1, l. 97, vol. i. p. 411), when to her sister Luciana she blames her husband Antipholus of Ephesus,— “What ruins are in me that can be found By him not ruin’d? then is he the ground Of my defeatures. My decayed fair A sunny look of his would soon repair.” In the _Cymbeline_ (act i. sc. 1, l. 130, vol. ix. p. 167), Posthumus Leonatus, the husband of Imogen, is banished with great fierceness by her father, Cymbeline, King of Britain. A passage between daughter and father contains the same notion as that in the Emblem of Camerarius,— “_Imo._ There cannot be a pinch in death More sharp than this is. _Cym._ O disloyal thing, That shouldst repair my youth, thou heap’st A year’s age on me!” Nil penna, ſed vſus. [Illustration: _Paradin, 1562._] The action of the ostrich in spreading out its feathers and beating the wind while it runs, furnished a device for Paradin (fol. 23), which, with the motto, _The feather nothing but the use_, he employs against hypocrisy. Whitney (p. 51) adopts motto, device, and meaning,— “The Hippocrites, that make so great a showe, Of Sanctitie, and of Religion sounde, Are shaddowes meere, and with out substance goe, And beinge tri’de, are but dissemblers founde. Theise are compar’de, vnto the Ostriche faire, Whoe spreades her winges, yet sealdome tries the aire.” A different application is made in _1 Henry IV._ (act iv. sc. 1, l. 97, vol. iv. p. 317), yet the figure of the bird with outstretching wings would readily supply the comparison employed by Vernon while speaking to Hotspur of “the nimbled-footed madcap Prince of Wales, and his comrades,”—
