Sir Thomas Wyatt's poetry has most often been analysed with reference to his biography, his sources and his imagery. I propose, for the first time, that linguistic features of his poems need to be taken Into account when evaluating Wyatt's contribution to English literature. In this thesis, I therefore analyse Wyatt's language. Including his vocabulary and syntax, and his use of rhetoric, concentrating on rhetorical structure and rhetorical devices. I employ statistical methods in order to arrive at verifiable conclusions, and, based on these conclusions, I endeavour to determine whether a number of anonymous poems can be attributed to Wyatt.
