[21] Galen was born at Pergamon, in the reign of the Emperor Hadrian. He studied medicine at Pergamon, Smyrna, and Alexandria, and for a time lived in Rome. Returning to Pergamon he was appointed physician to the athletes in the gymnasium there. He later went back to Rome and became physician to the Emperor Marcus Aurelius. He is credited with five hundred works on literature, philosophy, and medicine, one hundred and eighteen of which have survived. In medicine he wrote on anatomy, physiology, diagnosis, pathology, therapeutics, materia medica, surgery, hygiene, and dietetics. He was the first to use the pulse as a means of detecting physical condition.

[23] Often spoken of as Constantius Africanus. It is recorded that he studied the arts in Babylon, visited Egypt and India, and returned to his home in Carthage one of the most learned men of his age. Suspected of dealings with the Devil he fled to Salernum (c. 1065), taught there for many years, published many medical works of his own, and finally retired to the monastery of Monte Cassino, dying there in 1087.
[24] In 1064 a company of seven thousand is said to have started for the Holy Land.

[26] "From Clermont the enthusiasm spread over France like wildfire. Stirring preachers, whereof the most notable was Peter the Hermit, set all France, peasant and noble, to arming. It was the old gospel of Mohammed recast in Christian guise:—pardon for sin and the spoils of the infidel if victorious!—a swift road to heaven if slain in the battle! Pressed with this hope and enthusiasm, armies to be reckoned by the hundreds of thousands were launched upon the East." (Davis, W. S., Mediaeval and Modern Europe, p. 95).
[27] Of the thousands of petty lords and knights who went to the hot East, clad in the heavy armor of northern Europe, large numbers left their bones along the way or in the Syrian sands, and the landholdings at home reverted to the Crown. This was a crushing blow to the old feudal regime, advanced the cause of civilization, and helped in the rise of the modern nations. Especially was this true in France and England, whose knights went in large numbers to the East. In Germany the knights and nobles, as a class, refused to have anything to do with the Crusades, and hence they were not killed off or impoverished, but remained to rule and multiply and be troublesome. This is one reason for the much earlier rise and greater strength of French than German nationality, and one reason why Germany has been so much slower than France and England in developing a democratic type of civilization.
[28] "As presented to the eye, a typical mediaeval city would be a remarkable sight. Its extent would be small, both because of the limited population, and the need of making the circuit of the walls to be defended as short as possible; but within these walls the huge, many-storied houses would be wedged closely together. The narrow streets would be dirty and ill-paved—often beset by pigs in lieu of scavengers; but everywhere there would be bustling human life with every citizen elbowing close to everybody else. Out of the foul streets here and there would rise parish churches of marvelous architecture, and in the center of the town extended the great square—market-place—where the open-air markets would be held, and close by it, dwarfing the lesser churches, the tall gray cathedral— the pride of the community; close by, also, the City Hall, an elegant secular edifice, where the council met, where the great public feasts could take place, and above which rose the mighty belfry, whence clanged the great alarm-bell to call the citizens together in mass meeting, or to don armor and man the walls." (Davis, W. S., Mediaeval and Modern Europe, p. 146.)
[29] In Italy, in particular, the cities became strong and powerful, and eventually overthrew the rule of the bishops and defeated the German Emperor, Frederick I, in a long battle to preserve their independence. In Flanders such cities as Ypres, Bruges, and Ghent, came to dominate there. In 1302 their burghers defeated the French army; and in the sixteenth century they helped to break the autocratic power of Spain in a great struggle for human and civic freedom. By the thirteenth century Hamburg, Lübeck, Bremen, Augsburg, and Nuremburg were important commercial cities in Germany.
[30] They came there because, due to their plundering and murdering proclivities, Venice forbade her merchants to go to them.
