An alchemist in a calf-length robe holds up a book in one hand, reading with close attention as he stirs a substance in a small crucible. The tabletop beside him is littered with glassware and distillation vessels. In a well-stocked workroom, he stands beside a small furnace and in front of a wall hung with animal skulls and a candlestick, in which the candle has been burned to a nub. The drawing is subtly shaded and captures an atmosphere of quiet but diligent work.
