Only the Gospel of John, 2:1-11, tells of this first miracle of Jesus, marking the transition from a Galilean teacher to the Messiah to-be, "Jesus did this, the first of his signs, in Cana of Galilee and it revealed his glory and his disciples believed in him (John 2:11)".
Jesus, His mother and disciples are at a wedding in Cana. When the wine runs out He orders servants to fill containers with water and turns it into wine.
This mosaic panel suffered a poor mid-19th century restoration by Felice Kibel. There is a sharp diagonal transition between restoration and original, with jugs (of water being turned into wine) replaced by baskets!
