In Greek mythology one of Gaia’s daughters is Tethys, the sea or ocean. And Gaia dances with her daughter, this source of life, yet also this destroyer of life, for in this dance so many different facets can be displayed, so many different forms, patterns and textures; from absolute stillness, to the gentlest ripples, melodious waves and onto raging furious deadly torrents. And whilst I have never heard it stated, I suspect that, like snowflakes, no two waves are ever the same. Subtle differences in wind and tide and current will create subtle differences in the dance. Waves are mesmerising; I could watch them for hours.
