Discuss the use of lines, both actual and implied, to direct the viewers' eyes and to create focal points in the following two works by Leonardo da Vinci: The Last Supper and The Virgin and St. Anne with the Christ Child and John the Baptist

What will be an ideal response?

Focal points draw the viewer into the image, and lines, actual and implied, move the eye around the composition. The Last Supper uses actual and implied lines to create a linear perspective that emphasizes the focal point. The Virgin and St. Anne uses implied lines in the form of a triangle to contain the composition in addition to a circular motif of the heads.
