# To Ascot: double heliz...

• Hi Amelia,

When you look down from the top of a circular staircase (or conversely, if you look upward), that perspective will produce a logarithmic spiral. Light houses present lengthy windings. In the case of this one and Vatican Museum, in a sense there are a pair of intertwined helical spirals, in the manner of the DNA structure.

Many thanks for critique and the astute observation,

Many thanks for that little tit-bit of info re: the Golden Mean and the DNA molecule, Bulent. Most interesting
