This article provides an interesting interpretation of magnificent windows that are to be found in various churches, including King’s College, Cambridge. Henry VI, Edward IV, Richard III, Henry VII and Henry VIII had a royal hand in these masterpieces.
Henry VII, of course, went overboard with all his heraldic symbols, and at King’s College (see illustration above) he had all the usual Tudor badges on display, to which he added the hawthorn tree in which Richard III’s crown was supposedly found. Looking at the illustration, I suppose the greenery on the left depicts said hawthorn tree. Unless the hawthorn is in the part of the window that is not shown.
