The play was not published until the First Folio of 1623. In spite of tentative early datings, most critics believe the play is one of Shakespeare's later works, possibly written in 1610 or 1611. A 1611 date is suggested by an apparent connection with Ben Jonson's Masque of Oberon, performed at Court 1 January 1611, in which appears a dance of ten or twelve satyrs; The Winter's Tale includes a dance of twelve men costumed as satyrs, and the servant announcing their entry says "one three of them, by their own report, sir, hath danc'd before the King." (IV.iv.337-38). Arden Shakespeare editor J.H.P. Pafford found that "the language, style, and spirit of the play all point to a late date. The tangled speech, the packed sentences, speeches which begin and end in the middle of a line, and the high percentage of light and weak endings are all marks of Shakespeare's writing at the end of his career. But of more importance than a verse test is the similarity of the last plays in spirit and themes. Wikipedia
