This book is a modern Turkish translation of Istılâhât-ı Mi‘mâriyye, a work on architecture by Celâl Esad Arseven (1875-1971), one of the pioneers of Turkish art research. This book is more than just a dictionary; it not only reveals the meticulous work of an intellectual who dedicated almost a century of his life, from the Ottoman Empire to the Republic, primarily to the research of Turkish art and architecture, but also serves as an important reference book for those working on Ottoman architecture or architectural history. This work, which aims to uncover the architectural terminology of Ottoman civilization by consulting architects, masons, carpenters, calligraphers, and miniature painters living at the time it was written, not only revives the traditional memories and architectural practices of the past with rich visuals; it also guides those interested in the architectural history of the Ottoman era to a knowledgeable acquaintance with the architectural vocabulary of this era through terms, a significant part of which is now largely forgotten.
