This is a historical account of an empire that has been overlooked by many historians. Written by a contemporary writer and translated by Karl Friedrich Neumann, the book describes the life of Vahram, a native of Edessa, a priest, and the secretary of King Leon III. The book offers insight into the origin and growth of the Armenian kingdom. It includes commercial treaties made between the Armenian kings and Venetians and Genoese, which further highlight the kingdom's importance. The Armenian kingdom's history is closely linked to its warfare with the Byzantine Empire, with animosity between the two peoples lasting for centuries. It details the rise of the Bagratides, who established a new Armenian kingdom on Mount Taurus, which extended its boundaries to the sea coast, including the whole province of Cilicia. The book also offers insight into the imprisonment and release of the last Armenian king of Cilicia, Leon III., who died in Paris in 1393.
