Columns with twisted spiral shafts. A true barley sugar column, also known as a Salomonic column, is deeply incised and heavily spiralled. It is difficult to find good examples in Canterbury. Image 1 below is close to convincing, but image 2 is only lightly incised, sometimes known as a 'barber's pole' spiral. Image 3 seems (in the low light of the Cathedral crypt), to show signs of spiral incisions, but on close inspection does not - the spiral motif is simply painted on.
