Arms, hands [of the two van Gogh brothers Vincent and Theo], like rifles, thrust out like non-stop ideas thoughts. Enormous thick veins like the ropes of a ship through which flow thoughts and inspirational excitement. They join the two brothers like nerve connections that pass from one body to the other, channeling the waves and opening up both in a magnetic ring of work and passion.
