In The Beating Heart, Robin Choudhury explores how the heart has been represented over time and across cultures. He investigates the interplay between the heart depictions of successive eras and the prevailing cultural discourse – religious, social, philosophical – of each. In parallel, he considers how the 'scientific' understanding of the function of the heart has unfolded over 2,500 years, from the observations of Aristotle, through detailed anatomical descriptions beginning in the Renaissance, to the emergence of experimental physiology in the 17th century, culminating in the 20th in full understanding of the molecular and cellular processes by which the heart beats autonomously.
