“With Neither Hope Nor Fear”: Continuity In The Life Of Isabella D’Este, Alyssa Murphy

Electronic Theses and Dissertations

Isabella d’Este is traditionally viewed as the most notable female art patron of Renaissance Italy, primarily studied for her excellent taste. This positive interpretation has left her out of the reputational rehabilitation that modern historians have applied to many of her contemporaries, and what recent work has been done focuses on her marriage. However, Isabella outlived her husband by nearly twenty years, and contrary to writers who view that widowhood as an afterthought, she remained a dominant political and cultural figure in her own right. This thesis reassesses Isabella’s letters to argue that the traditional segmentation of her life does …

A Kinetic Analysis On Hydrolysis And Hydrothermal Conversion Of Cellulose To Dodecane, Joel Nyangoka Onyancha
