THE AGE OF EXPANSION 321 temples, and throughout their country there were magnificent works of public utility, such as roads, bridges, and aqueducts. Their government was a mild paternal autocracy. Their Spanish conquerors robbed and reduced them to abject slavery when they were not ruthlessly exterminated to make room for Negro slaves imported from Africa.1 From this tale of discovery and conquest we shall now turn to the more interesting intellectual developments of the age. " The widening of the physical horizon," as one writer has observed, " brought a corresponding extension of the in- tellectual horizon." The initial impulse for it likewise came from the East. The Turkish occupation of South-Eastern Europe had driven the Greeks westwards to ' Magna-Graecia' or South Italy. The fall of Constantinople brought in its train a large band of Greek refugees to Rome and the other Italian cities. Among these were not a few scholars who brought with them many valuable manuscripts of the Greek classics. This naturally evoked interest in the ancient Hel- lenic literature and culture among the Italians. That interest soon developed into a wider movement known as Humanism. It was so described because throughout the Middle Ages the best of the intellectuals had concentrated their energies on theological studies, whereas the new learning was centred round subjects of "human" interest. From this point of view Dante's Divina Commedia (noticed earlier), though it has been called the "Epic of Medievalism" was also a forerunner of the new movement in literature. Petrarch (1304-74) was even a greater representative of this human- ism. In fact he is considered the greatest of humanists. 1.
