"Hayl you (admired Heydon) whose great parts Shine above envy; and the common Arts, You kin to Angels, and Superiour Lights, (A spark of the first fire) whose Eagle flights Trade not with Earth, and grossness, but do pass To the pure Heavens, and make your God your Glass, In whom you see all forms, and so do give These rare discov'ries, how things move and live, Proceed to make your great designs compleat, And let not this rude world our hopes defeat. Oh let me but by this the dawning light Which streams upon me through your three pil'd night, Pass to the East of truth, 'till I may see Man's first fair state; when sage Simplicity The Dove and Serpent, Innocent and Wise Dwell in his brest, and he in Paradise. These from the Tree of knowledge his best boughs I'le pluck a Garland from this Author's brows, Which to succeeding times Fame shall bequeath, With this most just Applause, Great Heyden's wreath. FRED. TALBOT, _Esquire_." In the opening pages of the "Holy Guide," we find the following:-- "Renowned Eugenius! Famous above all! A Prince in Physiques! Most Seraphicall! The Art's Great Archer! Never shooting wide; Yet Hitt'st the White best, in thy Holy Guide. Good God! What Pains have learn'd Physitians For cleansing Physiques [strange perturbed] Brook? But as their crooked labours did destroy Our hopes, Thy Guide directs the Ready Way. Hippocrates, Great Galen, and Senertus, Rhenvoleus, Paracelsus, and Albertus, Grave Gerrard, and Ingenious Parkinson, Dead Culpeper, and living Thomlinson, Have all done well. But ah! they miss the Road, Thou Chalked out, Thou Dear Servant of God; And therefore 'tis no wonder, if they vary From thee; Great Nature (High born) Secretary! 'Tis thou alone, hast taught the way to bliss: 'Tis thou alone, that knowest what it is: 'Tis thou hast raked fruitful Egypt o'er For Medicines; and Italy for more; And in Arabia thy collecting Braines, To doe us good, hath taken wondrous Paines This having done, if Critiques will not bow To thy Great Learning Petra scandalou, It shall unto them surely prove: And this Essay of thy Sublimer Misteryes, Shall make them sure unto the Wise Minerva Yet still be ignorant of thy Pantarva. But hold! Where am I? Sure th' hast set a spell On me, cause I can't praise thy doings well: Release me, Good Eugenius! and the Crowne Shall stand on no browes but thy learned Owne. Poets, no more lay Claime unto the Bayes! 'Tis Heydon shines alone with splendid Rayes! Follow his Guide, he teaches you most sure; Let any make the Wound; 'Tis he must cure. For he directs the Welgrowne; Old, and Young, To live Rich, Happy, Healthy, Noble, Strong. JOHN GADBURY." "To the Reader on the behalf of my much honoured Friend the Author Mr. John Heydon."
