Why did mosaics tend to disappear and be replaced by paintings?

Mosaics tended to disappear and be replaced by paintings primarily due to changes in artistic preferences and techniques during the Renaissance. As the demand for more realistic and expressive forms of art grew, painting allowed for greater versatility in style and emotion, which mosaics could not easily replicate. Additionally, the decline of public and religious spaces where mosaics were traditionally used, along with advancements in painting materials and methods, facilitated the shift toward canvases and frescoes. This transition reflected broader cultural shifts towards Humanism and individual expression in art.
