The Chronicon (Chronicle) or Temporum liber (Book of Times) was a universal chronicle written by Jerome. It was one of his earliest attempts at history. It was composed c. 380 in Constantinople; this is a translation into Latin of the chronological tables which compose the second part of the Chronicon of Eusebius, with a supplement covering the period from 325 to 379. Despite numerous errors taken from Eusebius, and some of his own, Jerome produced a valuable work of universal history, if only for the example which it gave to such later chroniclers as Prosper of Aquitaine, Cassiodorus, and Victor of Tunnuna to continue his annals. In conformity with the Chronicon of Eusebius (early 4th century), Jerome dated Creation to 5201 BC.
The Chronicle includes a chronology of the events of Greek mythology, based on the work of Hellenistic scholars such as Apollodorus, Diodorus Siculus, and Eusebius. While the earlier parts are obviously unhistorical, there may be scattered remnants of historical events of late Mycenean Greece from entries of the 12th century BC. (See the historicity of the Iliad. Notably, Jerome's date for the capture of Troy of 1183 BC corresponds remarkably well with the destruction layer of Troy VIIa, the main candidate for the historical inspiration of legendary Troy, dated to c. 1190 BC.) Homer himself is dated to 940 BC, while modern scholarship usually dates him after 800 BC.
