English: Arms of the Dean and Chapter of Canterbury Cathedral (Azure, on a cross argent the Roman letters X surmounted by I in pale sable), recorded by the College of Arms during the Visitation of Kent in 1619, where they are listed in the heading as "Canterbury: Dean & Chapter" (with the text giving the full name as "the Denery & Chapter of the Cathedrall church of Christ in Canterbury") and blazoned as: Azure, on a cross argent a Roman letter X surmounted by the letter I sable. "Some accounts say that the letters on the cross are Greek (iota, chi) and stand for the initial of Jesus Christ. Others say that they are an abbreviation of Christi, and thus properly chi, iota; hence the lower case "i" in some versions" (Source: http://blog.appletonstudios.com/2019/02/the-arms-of-canterbury-cathedral.html#:~:text=The%20arms%20were%20recorded%20by,as%3A%20Azure%20on%20a%20cross).
