The subject, from the New Testament (John 2), is the scene of Christ's first miracle when he turned water into wine at the marriage feast in Cana. Christ is seated at the right; next to him is his mother, Mary, who had told the servants to do Christ's bidding. Christ asked to have six stone jars filled with water which, when tasted, was found to be wine of the finest quality.
Preti was much influenced by Veronese and frequently painted pictures of feasts. This one probably dates from shortly before 1660.
