The crusades also furnished material for poetic imagination and for literary products. It was the development of the old saga hero under new conditions, those of Christianity and humanity, and this led to greater and more profound sentiments concerning life. The crusades also took men out from their narrow surroundings and the belief that the Christian religion, supported by the monasteries, or cloisters, embodied all that was worth living in this life and a preparation for a passage into a newer, happier future life beyond. Humanity, according to the doctrine of the church, had not been worth the attention of the thoughtful. Life, as life, was not worth living. But the mingling of humanity on a broader basis and under new circumstances quickened the thoughts and sentiments of man in favor of his fellows. It gave an enlarged view of the life of man as a human creature. There was a thought engendered, feeble though it was at first, that the life on earth was really important and that it could be enlarged and broadened in many ways, and hence it was worth saving here for its own sake. The culmination of this idea appeared in the period of the Renaissance, a century later. {326} _The Commercial Effects of the Crusades_.--A new opportunity for trade was offered, luxuries were imported from the East in exchange for money or for minerals and fish of the West. Cotton, wine, dyestuffs, glassware, grain, spice, fruits, silk, and jewelry, as well as weapons and horses, came pouring in from the Orient to enlarge and enrich the life of the Europeans. For, with all the noble spirit manifested in government and in social life, western Europe was semibarbaric in the meagreness of the articles of material wealth there represented. The Italian cities, seizing the opportunity of the contact of the West with the East, developed a surprising trade with the Oriental cities and with the northwest of Europe, and thus enhanced their power.[1] From this impulse of trade that carried on commerce with the Orient largely through the Italian cities, there sprang up a group of Hanse towns in the north of Europe. From a financial standpoint we find that money was brought into use and became from this time on a necessity. Money-lending became a business, and those who had treasure instead of keeping it lying idle and unfruitful were now able to develop wealth, not only for the borrower but also for the lender. This tended to increase the rapid movement of wealth and to stimulate productive industry and trade in every direction.
