As the tradition of classical Gaelic poetry declined, a new tradition of vernacular Gaelic poetry began to emerge. While Classical poetry used a language largely fixed in the twelfth century, the vernacular continued to develop. In contrast to the Classical tradition, which used syllabic metre, vernacular poets tended to use stressed metre. However, they shared with the Classic poets a set of complex metaphors and role, as the verse was still often panegyric. A number of these vernacular poets were women, such as Mary MacLeod of Harris (c. 1615–1707).
