An old man 

This portrait, painted by Joseph Wright of Derby, is a compelling depiction of an elderly man, likely a self-portrait of the artist himself. The subject's thoughtful expression and furrowed brow suggest a deep contemplation, perhaps about the passage of time or the weight of experience. The man's white hair and beard add to his venerable appearance, emphasizing his age and wisdom. The soft lighting and subtle brushstrokes give the portrait a sense of intimacy and realism, characteristic of Wright's work.
