The gesture which we would reproduce on canvas shall no longer be a fixed moment in universal dynamism. It shall simply be the dynamic sensation itse… - Umberto Boccioni

Balla [his former art teacher in Italy] flabbergasted us because, not content with being involved in a Futurist campaign, as you can well imagine him doing, he launched himself into a complete transformation. He rejected all his works and all his working methods. He started work on four pictures of movement (one painting was his 'Girl running on a balcony'), which were still realist but incredible ahead of their time.. ..He confided this to w:Aldo Palazzeschi: 'They (Balla's former - so much younger pupils Boccioni and Severini] did not want anything to do with me in Paris and they were right: they have gone much further than I, but I will work and I too will progress.'

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.

Sculpture is based on the abstract of the planes and volumes that determine the forms, not their figurative value.
