This thesis is an edition of four poems (Lady Bessiye, Bosworth Feilde, Scotish Feilde, and Flodden Feilde) which were written in celebration of the military successes of the family of Stanley, Lords Stanley and Earls of Derby, at the battles of Bosworth (1485) and Flodden (1513). The introduction discusses the manuscripts and editions, the conditions for which the poems were composed, the style of the poems, and their contributions to the history of the period. The poems are newly edited, and the commentaries attempt, as well as elucidating the meanings of obscure lines, to identify the people and places which would have been of interest to the Stanley family and friends.
