Today is the feast of the martyrdom of St Thomas of Canterbury.
A recent post by Stephanie A. Mann at Supremacy and Survival: The English Reformation
dealt with the fact that it was the destruction of the shrine of St Thomas that was the last straw for Pope Paul III and led to the publication of the excommunication of King Henry VIII. It can be viewed at St. Thomas a Becket and the Long Delayed Excommunication of Henry VIII
There is a useful account by J.C.Wall from his Shrines of British Saints, published in 1905, of the shrine and its decoration, with contemporary illustrations and descriptions as well as an account of the Translation of the relics in 1220 which can be accessed at http://www.historyfish.net/shrines/cw_shrines_four4.html#thomas
The Shrine of St. Thomas of Canterbury.
Cottonian MS., Tib. E. viii. f. 269.
