High Quality Content by WIKIPEDIA articles! Pan`s Anniversary, or The Shepherd`s Holiday was a Jacobean era masque, written by Ben Jonson and designed by Inigo Jones. The date of the masque`s performance at the English Court has long been in dispute: while the earliest text assigns it to 1625, mid-twentieth-century scholars placed it on June 19, 1620, the king`s birthday, at the royal palace at Greenwich. More recently, Martin Butler has argued for a date of January 6, 1621.
