Step-by-step explanation:
Sir Joshua Reynolds (1723-1792) was a prominent English portrait painter who played a significant role in the Neoclassical movement.
Beyond his beautiful full-length portraits and children's paintings, Reynolds is noted for being a founding member and the first president of the Royal Academy of Fine Arts. His painting, Lady Sarah Bunbury Sacrificing to the Graces (1765), is an example of his work during this time, highlighting his ability to merge classical elements with contemporary portraiture.
A famous work that showcases Reynolds's Neoclassical style is his painting Lady Cockburn and Her Three Eldest Sons, which exhibits his proficiency in capturing the nobility and grace of his subjects.
