When his work was partly accomplished, and he was on the scaffolding to prepare for the turning of the vault, he fell with a mass of timber and stone from a height of 50 feet, and was disabled for life. He chose for his successor another man of genius, known as English William, one of his staff, "small of body, but in many kinds of workmanship acute and honest", who added to his master's design the great uplift of the floor of the Trinity Chapel and completed that and the Corona or Becket's Crown. Since 1185 no substantial alteration has been made in the eastern half of the Cathedral.
If the reader desires to know the chief sources of our information about the early history of Canterbury Cathedral, the reply is in itself a picture of the times. Eadmer was a boy in the convent school before the Conquest, and singer or precentor in Lanfranc's choir of monks. He also lived through the rule of Anselm.
Gervase was a monk of Christ Church when Becket died in the Martyrdom. He witnessed the fire of 1174, the desolation it left behind, and the immortal achievements of French William and of his English namesake. Eadmer and Gervase have both left us narratives, not umixed with monkish legend, but faithful and full of curious information.
It is not easy for us to understand the veneration paid to relics; yet from that veneration sprang all the glories of the Cathedral. And when we read in these old chronicles, translated from Latin in Willis' Architectural History, of the desperate, almost agonized labours of the monks to save from fire, weather, or dishonour the remains of their buried saints, we shall withhold our scorn for their superstition, and find less surprising the immense sums paid in the Middle Age for the arm or skull of a dead man.
THE GATEWAY, ST. AUGUSTINE'S ABBEY [(Page 51)]
The earlier Saxon archbishops were laid in the ground of St. Augustine's Abbey, which thus accumulated a store of sanctity which roused the sore jealousy of their Christ Church brethren. Accordingly in the eighth century Cuthbert obtained a secret permission from the Pope to be buried in the Cathedral. His death was not divulged until he was safely interred, and when the monks of St. Augustine's came to demand as usual the body of the dead archbishop, they were met with derisive shouts, and the brandishing of the Papal decree. Thus Gervase records that Cuthbert, "being endowed with great wisdom, procured for Christ Church the right of free sepulture".
There is at least one "secret chamber" in the Cathedral for the hiding away of relics or of treasures. This is the Chapel of St. Gabriel in the crypt. The entrance was through a hole which was entirely concealed by an outside altar. This chapel was so successfully hidden that the monk Gervase was evidently ignorant of its existence in the twelfth century; and its roof is covered with very curious painting of that date, which the darkness (for there is no window) has kept in remarkable preservation. There is also a room, over the Treasury, accessible only by a door opening 6 feet above the floor of St. Andrew's Chapel, requiring therefore a ladder as means of approach. But it was never a really secret chamber, and was probably at one time entered by an ordinary stone stairway.
