Featuring miniature works, the book is over 50 pages honoring Ottoman Sultan Mehmed the Conqueror's 49-year life. There are three portraits of Mehmed II, calligraphic descriptions of his three tughras (seals) and miniatures of his mother Hadice Hüma Hatun, his father Sultan Murad II, Grand Vizier Mahmud Pasha and his scholar advisors including Mollah Hocazade, Mollah Gürani, Akşemsettin, Mollah Hüsrev, Mollah Zeyrek and Ali Kuşçu. Ünver published the book in 1953 as a tribute to the 500th year of the conquest of Constantinople. Aside from the Ottoman miniatures, the unique ornamentations on the corners and edges of the pages are also eye-catching elements of the author's work. In aprevious statement, Ünver said he prepared only one copy, as if he was going to present it to Sultan Mehmed II. The late professor wanted to record the nation's intangible cultural asset and said that each historical artifact should be turned into a written document. This is because he created a number of works on the history of Islam and the Ottoman Empire. He further showed his artistic skills by adding his watercolor paintings to his work, bringing them a visual character.Among his writings, "The Notebook of the Conqueror" is recognized as the most important one and was republished in its original form with the contributions of Professor İsmail Kara. Ünver's daughter Gülbün Mesara previously recorded her father's descriptions of miniatures and these were also added to the latest version of the book. Ünver's book features drawings of the Fatih Mosque, Harbi prayer room, a mosque in Çanakkale, the madrasahs in the Fatih district, the treasury of Topkapı Palace, Bab-ı Hümayun (Imperial Gate), Cihannüma Mansion of the Edirne Palace, Çinili Mansion, the old imperial palace, the Rumeli Fortress, the Yedikule neighborhood, Ottoman guest houses and hospitals.
