"So the heart is the beginning of life, the Sun of the Microcosm,
even as the Sun deserves to be call'd the heart of the world;
for it is the heart by whose virtue and pulsation the blood is moved, perfected,
made apt to nourish, and is preserved from corruption and coagulation;
it is the household divinity which, discharging its function, nourishes, cherishes,
quickens the whole body, and is indeed the foundation of life, the source of all action."
~ William Harvey, 1628/Programming by DPC
