The Alchemists 

"The Alchemists" by Pietro Longhi, a Venetian painter known for his genre scenes, is a depiction of three men engaged in alchemical experimentation. The scene is set in a dimly lit laboratory, with a fireplace and various apparatuses visible. One man stirs a mixture in a crucible over a fire, while another holds a glass flask, and a third observes intently, highlighting the intrigue and mystery surrounding alchemy. The painting offers a glimpse into 18th-century Venetian society and the fascination with the transformative powers of chemistry.
