This is the most famous depiction of the Last Supper, Christ's last meal before his crucifixion. During this meal, Christ shared bread and wine with his disciples in a gesture that formed the basis for the Christian rite of Communion. Christ is seated at the crnter of the table, flanked by the apostles. The Renaissance fascination with geometry and composition is reflected in the fact that the lines formed by the ceiling, if extended, meet at a point on Christ's head.
