what is a portrait in art and how does it reflect the era?

In the realm of art, a portrait is not merely a likeness or an image of a person; it is a window into the soul of the subject, capturing not only their physical appearance but also their essence, personality, and spirit. The portrait serves as a mirror reflecting the societal norms, cultural values, and historical context of its time, thus offering us a profound insight into the world through the eyes of those depicted.
