The published play is a rewritten version of
Gismund of Salerne, of which two manuscript copies survive, that was written and produced by five members of the Inner Temple for Queen Elizabeth during the
revels entertainments. Each act was written by a different author, named respectively as Rod. Stafford, Hen. Noel, G. Al., Ch. Hatton, and
Robert Wilmot. The play was revised in keeping with "the decorum of these daies" by recasting the original rhyming lines into blank verse. Earlier critics dated the original play 1567-8 by taking Wilmot's prefatory reference to his fellow Inner Temple collaborators to "the loue that hath bin these 24 yeres betwixt vs" and working back from the publication date. Chambers dates the play earlier to Shrovetide, between 24 and 26 February 1566 from an allusion in the manuscript to its performance at Greenwich and matching that to Elizabeth's itinerary. ==References==
