A brief supplement to the Two Oldcastles of London

Abstract My previous investigations of the history play Sir John Oldcastle (Ilsemann, 2017) that were carried out with Rolling Delta and Rolling Classify, are viewed again and supplemented by the results of the General Imposters method and the investigations of Lupić in 2018. The Shakespearean character of the play is also supported by Oldcastle n-grams from Rizvi’s data bank which match Much Ado About Nothing (1598), Julius Caesar (1599), Henry V (1599) and As You Like It (1599).
