Final answer:
It is true that artists have historically included symbols and moral lessons in their paintings, offering layers of meaning for viewers to decipher. This practice can be seen in various art periods, including the Dutch Golden Age and in the themes of 19th-century American art.
Step-by-step explanation:
The assertion that artists painted familiar scenes such as home, work, and the marketplace, while also embedding symbols and moral lessons into their artwork, is true. Throughout history, artists have often sought to portray more than just the visible world. They have imbued their works with additional layers of meaning, offering viewers the opportunity to engage in interpreting these messages.
During the Dutch Golden Age, for example, genre paintings often included such symbolism to reflect moral lessons or commentaries on society. Similarly, the emergence of new art movements and themes of democracy, the modern man, and national identity in American artworks of the 1800s reflect a move away from solely religious motifs towards subjects that the growing middle class could relate to and appreciate.
