Aristotle supposed that winds were analogous to rivers in that each was a largely contained system with its own idiosyncrasies. In early modern texts, however, the emphasis is rather different. Wind was far from being an element of the definition of storms as in today's language. William Fulke goes on to describe the pleasantness of this wind, which seems to be what we would now call a summer breeze. Fulke's approach to the causes of wind seems to have persuaded his contemporaries and followers. Roger Warren glosses Gower's note of the wind's direction as 'north wind'. In Richard Hakluyt's Principal Navigations, a voyage to Tripolis is described as troubled by tempest, as 'presently there arose a mighty storme, with thunder and raine, and the wind at North'. The north wind might be understood in another way, as shown by John Deacon in his 1601 work, Dialogicall Discourses.
