It has been generally assumed that in the Morrell of the July eclogue of the Shepheardes Calender Spenser intended to satirize Dr. John Aylmer, bishop of London at the time of the composition and publication of this poem. Morrell's antagonist in this eclogue, Thomalin, has usually been considered a Puritan, but the Puritan so honored has been a matter of dispute among those scholars bold enough to hazard an identification. In this article I intend, first, to present in detail the grounds for Spenser's presumed dislike of Aylmer and to indicate Spenser's probable attitude towards him; second, to suggest that Dr. Thomas Cooper, bishop of Lincoln between 1571 and 1584, and definitely not a Puritan, is a more probable Thomalin.
