Neptune 

Giovanni Battista Piranesi, a renowned Italian architect and etcher, is best known for his dramatic depictions of Roman ruins. His etching "Neptune" is a striking depiction of the Roman god of the sea. The engraving showcases Neptune with his trident riding a seashell drawn by a serpent and two horses. The work is an example of Piranesi's mastery of the etching technique, a process that allows the artist to create intricate details and a sense of depth. This print is a testament to Piranesi's artistic skill and his fascination with the mythology and architecture of Ancient Rome.
