The document discusses the emergence of secular portraiture as a popular genre in 15th century Netherlands and Italy. During the Renaissance, wealthy patrons commissioned portraits to commemorate their accomplishments and express pride and self-worth, as individuals were not considered important enough to be depicted in art during the Middle Ages. Typical characteristics of Flemish portraits included realistic details of clothing and settings to convey wealth, as well as solemn expressions that communicated seriousness and piety. Jan van Eyck was renowned for his innovative portrait of Giovanni Arnolfini and his wife, which included symbolic details and innovative use of perspective that created an impressively convincing sense of space.
