Short answers, pulled from the story.
The Macedonian Renaissance was a period of cultural and intellectual revival in the Byzantine Empire during the 9th through 11th centuries. It unfolded under the Macedonian dynasty, which ruled from 867 to 1056. Scholars also call it the Middle Byzantine Renaissance or the First Byzantine Renaissance, distinguishing it from the later Palaeologan Renaissance, which began in the 13th century.
Kurt Weitzmann coined the term in 1948, in his study titled The Joshua Roll: A Work of the Macedonian Renaissance. Some scholars prefer alternatives such as "renascence" or "Middle Byzantine Renaissance." They note that the word Renaissance was coined by Italian humanists in the 15th and 16th centuries to describe their own era.
Basil I founded the Macedonian dynasty in 867, born in Thrace to a peasant family of paternal Armenian descent. He rose through the court of Emperor Michael III, became co-emperor, and died in 886. His dynasty created the political stability that allowed the arts, scholarship, and architecture of the Macedonian Renaissance to flourish.
Major buildings of the period include the Nea Ekklesia, commissioned by Basil I and built between 876 and 880 (now lost), and the Myrelaion church and palace complex, built between 913 and 922. Three surviving churches in Greece represent the later peak of Macedonian architecture: Nea Moni, Hosios Loukas, and the Daphni Monastery all date from the late 10th through the mid-11th century.
Byzantine encyclopaedism, a term introduced by the scholar Paul Lemerle, refers to the systematic effort to organize knowledge across all domains during the Macedonian Renaissance. It produced the Taktika, the Geoponika, the Suda encyclopaedia, the Bibliotheca, and the Basilika, among other compilations. Emperor Constantine VII Porphyrogennetos exemplified this spirit, producing three encyclopaedic manuals: the De Administrando Imperio, the De Thematibus, and the De Ceremoniis.
Alexander Kazhdan observed that the emphasis of the Macedonian Renaissance "was not on creativity, but on copying and collecting." This captures the era's dominant impulse: rather than inventing new knowledge, Byzantine scholars gathered, organized, and preserved the learning of earlier periods.
