Corn Cob, Reference to DNA

See Rosslyn Chapel.

Spiral carving around pillars depicts a double helix revealing the structure of DNA, indicating knowledge of science not discovered until hundreds of years after the chapel's construction.

Studying the photos shows that the column actually has a quadruple helix with one strand at each corner, not a double helix. A twisted pillar, known as a Solomonic or barley-sugar pillar, and has an old association with the Temple of Solomon in Jerusalem.
