The line of history, the Historia of lines

A stone with a line.
It comes from a massive piece of Earth’s surface, a mountain. It fell, it rolled. The river shaped it, roundish.

Tim Ingold wrote that "any history of the lines has to start with the relations between lines and surfaces".

Many stones and many ways.

A point can never be a line, a line can never be a surface, a surface can never be massive.

Mass becomes surface, made of lines, discrete.

Between my perception and my understanding, the timelines of my thinking appear to be fragmented.
