P. L. Jacob, The Arts in the Middle Ages and at the Period of the Renaissance
“ From the twelfth century, Pisa gave an impetus to the art by building its Duomo, its Baptistery, its Leaning Tower, and the cloisters of its famous Campo Santo; so many admirable works forming an era in the history of modern art, and in a brilliant manner opening the career on which so many distinguished men were to enter, rivalling each other in invention, in science, and in genius. In these monuments the union of Oriental taste with the traditions of ages gone by created an originality as grand as it was graceful. ”
