First Aldine edition of Pontano's collected philosophical works, dialogues and orations. The text was edited by Gian Francesco Torresani. The contents include Pontano's considerable political work, such as De principe , De liberalitate , and De magnanimitate , and his speculative and theoretical works on art and language such as De aspiratione , and De sermone . De immanitate , are considered the clearest Renaissance statement on the subject. The five dialogues cover a range of subjects, from metrics to the political role of clergy.
Complete sets are very rare.
Bound in contemporary vellum, titled in manuscript on spine and on top board. Defunct library stamp on title page. Moderate wear, with uniform discoloration and occasional foxing. Vellum cleft at base of spine. This bizarre work is, so far as we can tell, a unique form in literature.
