Some images of harmonious sea views, waves and light;

I would argue that the aesthetic of harmony in architecture is closely related to proportion, as in the conjunction of  forms
through numbers, and the use of semicircles, wave forms and radiating patterns, see my book here. This first view is
considered but discounted by Edmund Burke, in his "Philosophical Enquiry into the Origin of Our Ideas of the Sublime
 and the Beautiful".

"but it is in vain that we search here for any proportion between the height, the breadth, or anything else concerning the
dimensions of the whole, or concerning the relation of the particular parts  to each other" (Section 2)

In the case of seascapes, the above images appeal to our idea of the sublime, considered here, but also to a sense of harmony
due to the conjunction of coastline and islands, the presence of waves, and the light of the sun striking the sea. Light itself, seen
at sunset can present itself in harmonious geometric patterns. Another important commentator on aesthetics, George Ruskin, in
 "The Seven Lamps of Architecture" describes beauty as an "aspiration towards God expressed in ornamentation drawn from
 nature, his creation". Ruskin's naturalism is a good aesthetic critia, but I would argue that the religous sentiment is less important
 than in the case of the sublime, and unlike Coleridge, fails to use a geometric analogy.
