While the Byzantine MSS. of the 11th century (such as the Laurentian MSS. of Aeschylus and Sophocles, and the Ravenna MS. of Aristophanes) maintain the sound traditions of the Alexandrian and Roman ages, those of the times of the Palaeologi give proof of a frequent tampering with the metres of the ancient poets in order to bring them into conformity with theories recently invented by Moschopulus and Triclinius. The scholars of these times are the natural precursors of the earliest representatives of the Revival of Learning in the West. Of these later Byzantines the first in order of date is the monk Planudes (d. 1330), who devoted his knowledge of Latin to producing excellent translations of Caesar's _Gallic War_ as well as Ovid's _Metamorphoses_ and _Heroides_, and the classic work of Boëthius; he also compiled (in 1302) the only Greek anthology known to scholars before the recovery in 1607 of the earlier and fuller anthology of Cephalas (fl. 917).
The scholars of the Byzantine age cannot be compared with the great Alexandrians, but they served to maintain the continuity of tradition by which the Greek classics selected by the critics of Alexandria were transmitted to modern Europe.
(b) _In the West_ (c. 530-c. 1350).--At the portal of the middle ages stands Gregory the Great (c. 540-604), who had little (if any) knowledge of Greek and had no sympathy with the _secular_ side of the study of Latin. A decline in grammatical learning is exemplified in the three Latin historians of the 6th century, Jordanes, Gildas and Gregory of Tours (d. 594), who begins his history of the Franks by lamenting the decay of Latin literature in Gaul. The historian of Tours befriended the Latin poet, Venantius Fortunatus (d. _c._ 600), who is still remembered as the writer of the three well-known hymns beginning _Salve festa dies_, _Vexilla regis prodeunt_, and _Pange lingua gloriosi proelium certaminis_. The decadence of Latin early in the 7th century is exemplified by the fantastic grammarian Virgilius Maro, who also illustrates the transition from Latin to Provençal, and from quantitive to accentual forms of verse.
While Latin was declining in Gaul, even Greek was not unknown in Ireland, and the Irish passion for travel led to the spread of Greek learning in the west of Europe. The Irish monk Columban, shortly before his death in 615, founded in the neighbourhood of Pavia the monastery of Bobbio, to be the repository of many Latin MSS. which were ultimately dispersed among the libraries of Rome, Milan and Turin. About the same date his fellow-traveller, Gallus, founded above the Lake of Constance the monastery of St Gallen, where Latin MSS. were preserved until their recovery in the age of the Renaissance. During the next twenty-five years Isidore of Seville (d. 636) produced in his _Origines_ an encyclopaedic work which gathered up for the middle ages much of the learning of the ancient world.
