The Sacrifice of Melchizedek is a oil on canvas painting by Giovanni Battista Tiepolo (1696–1770), created in 1740. Measuring 525 × 100 cm, it depicts the biblical scene from Genesis 14. This painting is housed at Basilica San Lorenzo, Via Roma, Verolanuova.
The Sacrifice of Melchizedek is shown here as a pendant to the Gathering of Manna. The Priest-King of Salem brings Abraham bread and wine on the evening following the Battle of the Kings, and blesses him. Abraham, who kneels before him in armor, and the army to the right are a reminder of the battle which went before. To the left, we see the civilian population, including women, children and the elderly, while a triumphal procession is already approaching from behind the altar.
