Not only were the roads and bridges kept in the most perfect order throughout his territories, so as to facilitate locomotion, but on the frontiers and along the chief lines of route guard-houses were built and garrisons maintained for the express purpose of securing the safety of travellers.
The result was that the court of Chosroes was visited by numbers of Europeans, who were hospitably treated, and invited, or even pressed, to prolong their visits.
To the proofs of wisdom and enlightenment here enumerated Chosroes added another, which is more surprising than any of them.

He studied philosophy, and was a patron of science and learning.

Very early in his reign he gave a refuge at his court to a body of seven Greek sages whom a persecuting edict, issued by Justinian, had induced to quit their country and take up their abode on Persian soil.

Among the refugees was the erudite Damascius, whose work De Principiis is well known, and has recently been found to exhibit an intimate acquaintance with some of the most obscure of the Oriental religions.

Another of the exiles was the eclectic philosopher Simplicius, "the most acute and judicious of the interpreters of Aristotle." Chosroes gave the band of philosophers a hospitable reception, entertained them at his table, and was unwilling that they should leave his court.
