To compensate for the absence of large windows, interiors were brightly painted with scenes from the Bible and the lives of the saints. Later, the Basilique Saint-Denis marked a new trend in cathedral building when it utilized Gothic architecture.[100] This style, with its large windows and high, pointed arches, improved lighting and geometric harmony in a manner that was intended to direct the worshiper's mind to God who "orders all things".[100] In other developments, the 12th century saw the founding of eight new monastic orders, many of them functioning as Military Knights of the Crusades.[101] Cistercian monk Bernard of Clairvaux exerted great influence over the new orders and produced reforms to ensure purity of purpose.[101] His influence led Pope Alexander III to begin reforms that would lead to the establishment of canon law.[102] In the following century, new mendicant orders were founded by Francis of Assisi and Dominic de Guzmán which brought consecrated religious life into urban settings.[103]
