In the period 867-1025 the Byzantine chronological tradition continued. Herein we have to place the work of Joseph Genesios as well. The offspring of a noble family of the 9th-10th centuries from Constantinople and related to the family of Constantine VII Porphyrogennetos. The latter ordered Genesios to write the history of 9th century's Byzantine emperors up to the foundation of the Macedonian dynasty by Basil I, work that he indeed carried out. His work, however, corresponds more to the calls of a chronicle rather than to those of a historical work: as the sources he mentions include information provided by elderly people or rumours, while his historical narration swarms with prophecies, visions, auspices and impressive relations. Another chronicle, with the title "From the Creation of the World up to 948" still exists nowadays under the name of Symeon the Magistros and Logothete. This, however, presents a difficult scientific problem: in this text there are many manuscrtipts, each bearing the name of a different writer. Thus, the enigma regarding the author of the whole work- consisting of several parts- has not yet been resolved.
One last important chronographic work of the 10th century are the six historical chapters under the collective title "Scriptores post Theophanem/Theophanes Continuatus". They were written by order of the emperor Constantine VII Porphyrogennetos and, as their title shows, continued the chronicles of Theophanes, covering the period 813-961. Four of them were written under the supervision of the emperor. The fifth (the biography of Constantine' grandfather, Basil I, under the title "Historic narration of the Basil's -of the ever memorable King- life and actions") was written by Constantine himself. The sixth was written half by an anonymous writer and half by the eparch Theodore Daphnopates. This chronography - or at least the first five chapters - were compiled based on the material of Constantine' historic library, so much interesting information can be gleaned. It was written, however, not due to scientific interest but rather for the general public, aiming to promote political propaganda in favour of the Macedonian dynasty. Therefore, it has to be encountered with caution.
