   • c. 1599–1602 (date written), William Shakespeare, “The Tragedie of Hamlet, Prince of Denmarke”, in Mr. William Shakespeares Comedies, Histories, & Tragedies […] (First Folio), London: […] Isaac Iaggard, and Ed[ward] Blount, published 1623, →OCLC, [Act III, scene ii]:

     Hamlet:
     […] There is a play to-night before the king;
     One scene of it comes near the circumstance
     Which I have told thee of my father's death:
     I prithee, when thou seest that act afoot,
     Even with the very comment of thy soul
     Observe mine uncle: if his occulted guilt
     Do not itself unkennel in one speech,
     It is a damned ghost that we have seen,
     And my imaginations are as foul
     As Vulcan's stithy. Give him heedful note;
     For I mine eyes will rivet to his face,
     And after we will both our judgments join
     In censure of his seeming.
