Horizontal Quotes
I remained there [in The Netherlands, 1914-18] for the duration of the war, continuing my work of abstraction in a series of church. facades, trees, houses, etc. But I felt that I still worked as an Impressionist and was continuing to express particular feelings, not pure reality. Although I was thoroughly conscious that we can never be absolutely 'objective', I felt that one can become less and less subjective, until the subjective no longer predominates in one's work. More and more I excluded from my painting all curved lines, until finally my compositions consisted only of vertical and horizontal lines which formed crosses, each separate and detached from the other. Observing sea, sky and stars, I sought to indicate their plastic function through a multiplicity crossing verticals and horizontals.
Piet Mondrian
The simultaneousness of states of mind in the work of art: that is the intoxicating aim of our art... In the pictorial description of the various states of mind of a leave-taking, perpendicular lines, undulating lines and as it were worn out, clinging here and there to silhouettes of empty bodies, may well express languidness and discouragement. Confused and trepidating lines, either straight or curved, mingled with the outlined hurried gestures of people calling to one another will express a sensation of chaotic excitement. On the other hand, horizontal lines, fleeting, rapid and jerky, brutally cutting in half lost profiles of faces or crumbling and rebounding fragments of landscape, will give the tumultuous feelings of the person going away.
Umberto Boccioni
