Dionysius of Fourna (Greek: Διονύσιος ὁ ἐκ Φουρνᾶς; c. 1670 – after 1744) was an author, educator, painter, and monk.

His contemporary at the time was the painter David both artists belong to a class of their own.

His student and coworker was famous Greek painter Kyrillos Foteinos.

[6] Dionysius's famous book Interpretation of Painting Art (Ερμηνεία της Ζωγραφικής Τέχνης) attempts to provide a synthetic (or "harmonized") Gospel account of the life of Jesus Christ.

His timeline and events are mainly from the Book of Matthew, but he weaves in major incidents from the other synoptic Gospels.

The first part of the work gives recipes for colors, gesso, and instructions on body proportions for human figure painting.

The second part is a manual for the life of Christ, descriptions, and inscriptions for various Biblical and hagiographic subjects, and suggested images.
