This painting of The Unconscious Patient (Allegory of Smell) from about 1624 is believed to be Rembrandt’s earliest signed work, completed when he was only 18. It shows a barber-surgeon’s assistant trying to revive a patient from unconsciousness using smelling salts – a particularly pungent aroma. Three of the other paintings in this series were well-known, but two had apparently gone missing. This was re-discovered in 2015, but that of taste remains lost.
