The Beheading of Saint John the Baptist is an oil painting by the Italian artist Caravaggio. Measuring 3.7 m by 5.2 m, it depicts the execution of John the Baptist. It is located in the Oratory of St. John's Co-Cathedral in Valletta, Malta. According to Andrea Pomella in Caravaggio: An Artist through Images (2005), the work is widely considered to be Caravaggio's masterpiece as well as "one of the most important works in Western painting." Jonathan Jones has described The Beheading of Saint John the Baptist as one of the ten greatest works of art of all time: "Death and human cruelty are laid bare by this masterpiece, as its scale and shadow daunt and possess the mind." Composition The painting, in oil on canvas, is by and prominent are the vivid red and warm yellow colours, common to the Baroque period with the use of chiaroscuro. The image depicts the execution of John the Baptist while nearby a servant girl stands with a golden platter to receive his head. Another woman, who has been identified as Herodias or simply a bystander who realizes that the execution is wrong, stands by in shock while a jailer issues instructions and the executioner draws his dagger to finish the beheading. The scene, popular with Italian artists in general and with Caravaggio himself, is not directly inspired by the Bible, but rather by the tale as related in the Golden Legend. It is the only work by Caravaggio to bear the artist's signature, which he placed in red blood spilling from the Baptist's cut throat. There is considerable empty space in the image, but because the canvas is quite large the figures are approximately life-sized. Caravaggio drew the background for his work from his memories of his time in a prison of the Knights of Malta. Characteristically of his later paintings, the number of props and the detail in the props used is minimal. History Completed in 1608 in Malta, the painting had been commissioned by the Knights of Malta as an altarpiece; it was the largest altarpiece which Caravaggio would ever paint. It still hangs in St. John's Co-Cathedral, for which it was commissioned and where Caravaggio himself was inducted and briefly served as a knight. Caravaggio's service to the Order was brief and troubled, however, as he was soon a fugitive from justice, having escaped while imprisoned for an unrecorded crime.
