In 1969 he traveled to France to examine the construction history of Chartres cathedral, to see if the art-historical theories could be reconciled with the evidence in the masonry, and quickly found that the theories current at that time were incorrect. He continued this investigation at Chartres for five years, and developed the investigative technique he termed "Toichology". His first article on this research was published by
Dennis Sharp in the Architecture Association Quarterly in 1972, which led to
Robert Branner's assessment on what this approach could offer to scholarship. James showed how the cathedral had been built from the evidence in the masonry, and in the process redefined the constructional history of the building and presented a new view of early medieval building practice. He identified the nine master masons and analyzed their geometric methods. The monograph was published in two volumes in English, and three in French translated by local architect Dominique Maunoury. The major discoveries that caused controversy were:- • The cathedral was built in tilted, almost annual, layers, each layer being the work of a different master mason, some of whom returned from time to time. • The nave and the choir were built at the same time, not one after the other, and with the transepts and their porches, which were not added later. • That geometry ruled every design decision, including the initial geometry in setting out, and the bent axis was deliberate from the beginning. • The Royal Portal was not moved, but was erected where it is today with the western towers. • The apogee of Gothic sculpture should therefore be dated to the reign of
Phillipe Auguste, and not
Saint Louis, that is, some two decades earlier. In his study of Chartres he used his building experience and drafting ability to produce over 300 measured drawings to demonstrate not only the history of the cathedral, but to construct an investigative technique for medieval architecture. His work is akin to that of the French archéologues who focus on archaeological analysis, a group including
Arnold Wolff, Richard Hamman-MacLean and Jan van der Meulen. Their work commonly appeared in the monograph form, a "congenial vehicle for exercising the most precise and detailed examination of a great church's fabric". James determined that permanent architects did not exist for most Gothic churches before 1240, but that nearly all ecclesiastical buildings were constructed by bands of contractors who moved from site to site with their workforce. It was a major revision to the accepted opinion that discontinuous contracting was the norm. Though James had received a three-year training in Art History and was a skilled architect/builder for thirteen years, his views came up against the established canons of the profession. Some historians have still not accepted the thesis, though it has been obvious to professional architects. Some termed his views "eccentric", or "unusual", principally Steven Murray and
Lon Shelby, was mainly based on theoretical grounds, without any re-examination of the evidence in the structure itself. Through the discussions that followed, James recognized the greater complexity of the medieval building scene. Yet, as all his later work shows, he remains firmly convinced that builders, like carvers, were peripatetic, and that at least before the mid-thirteenth century design control was not held by a single permanent master. James' demotion of the architect as prime designer may have inadvertently been driven by the popular "death of the artist" notion among art historians of the 1970s and 1980s. To gain a deeper appreciation of the medieval experience, he took his family on the pilgrimage route from Chartres to Compostella (walking over 400 kilometers) in 1973. From 1977 James presented his findings at lectures at over 70 universities and colleges in the US, France, England and Australia, including Oxford, Harvard, Princeton and Berkeley. From these lectures he wrote a more popular history of Chartres. He hoped to repeat this approach on the cathedral of
Durham, Southwell Minster, and a group of key buildings in France associated with Chartres, in particular
Saint-Denis-en-France and Notre-Dame-du-Fort in Etampes. Appointed to various teaching and research posts at a dozen universities. ==
