Old Quebec by Gilbert Parker — Read

Living in the twentieth century, to which the uttermost parts of the earth are revealed, and with only the undiscovered poles left to lure us on, we cannot fully appreciate the geographical ignorance of the Middle Ages. The travels of Marco Polo had only lately revealed the wonders of the golden East, and in the West the Pillars of Hercules marked earth's furthest bound. Beyond lay the _mare tenebrosum_, the Mysterious Sea, girding the level world. England was not then one of the first nations of the earth. She was not yet a maritime power, she had not begun the work of colonisation and empire: the fulcrum of Europe lay further south. But as our Tudor sovereigns were making secure dominion in "these isles," the Byzantine Empire was moving slowly to its end, and favouring circumstances were already making Italy the centre of the world's commerce and culture.

There the feudal system, never deeply rooted, was declining slowly, and Italian energy and enterprise now having larger opportunity, seized the commerce of the East as it received vast impulse from the Crusades, and this trade became the source of Empire.
