In einem Brief an Francis Bacon am 14.Februar 1619 aus Brüssel fügte Mathew seinem Brief ein Bühnen-Manuskript bei “ The Duke of Lerma, („….to offer this inclosed paper to your sight, concerning the Duke of Lerma which ….will not, I think, be altogether unpleasing, because it is full of particular circumstances…“) und klärte Bacon in einer Fussnote über das Stück auf ( " I have out of a ragged hand in Spanish translated it, and accompanied it with some marginal notes for your Lps. greater ease." )
1668 wurde seltsamer Weise ein Theaterstück „The Great Favourite, or, the Duke of Lerma" (1668) zum ersten Mal gedruckt, dessen Autor nicht Tobie Mathew sondern Robert Howard war. ,„written by the honourable Sir Robert Howard“. In dem Vorwort („To the Reader“) der ersten Ausgabe 1668 liess Howard erkennen , dass das Stück nicht von ihm selbst sei : “I was concerned to let the world judge what subject matter of offence was contain’d in it: some were pleas’d to believe, little of it mine: but they are both obliging to me; though perhaps not intentionally……For the subject, I came accidentally to write upon it; for a Gentleman brought a Play to the Kings Company, call‘d the Duke of Lerma; and by them I was desir’d to peruse it, and return my opinion wether I thought it fit for the Stage,.( …) the Names, my altering the most part of the characters, and the whole design, made me uncapable to use much more; though perhaps written with higher Stile and Thoughts, then I cou'd attain to,(...)
But writing this epistle in so much a haste, I had almost forgot one Argument, or Observation, which that Author has most good fortune in it; It is in his Epistle Dedicatory, before his Essay of Dramaticke Poesie; where speaking of Rhyme in Playes, he desires it may be observ’d , That l…. which as to myself and him I easily acknowledge; for I confesse, none has written in that way better than himself, nor few worse than I: Yet, I hope, he is so ingenious that he would not wish this Argument should extend further than to him and me;
Was mag der Grund dafür sein, dass die Literaturwissenschaft bis heute keinerlei Verbindung des Stückes zu Tobie Mathew hergestellt hat?
Da das Shakespeare/Marlowe Buch (Seite 571-589) die pausible These entwickelt, dass der verdeckt schreibende Marlowe/alias Shakespeare später unter dem incognito Namen Tobie Mathew lebte, würde dies bedeuten, dass der wahre Shakespeare letztendlich der wahre Autor des "Herzogs von Lerma " war.-
