Earthly Vanity and Divine Salvation (Memling)

Earthly Vanity and Divine Salvation is a 1480s painting by the German-born citizen of Bruges, Hans Memling. It is on display in the Musée des Beaux-Arts of Strasbourg, France. Its inventory number is 185.
Overview.
The work consists of six isolated panels which had originally been arranged recto-verso as pairs and were sawn apart at some point before 1890. Neither the order of the panels from left to right, nor the coupling of the pairs of paintings, is known with certainty; and because of the work's theological content, it is disputed if it was designed as a triptych or as a polyptych. "Earthly Vanity and Divine Salvation" has generally risen and still raises more questions among art historians than almost any other work of its century, or any century.
As it exists now, "Earthly Vanity and Divine Salvation" consists of a narrative sequence (Vanity is followed by Death, which is followed either by Hell or by the Redemption through Jesus; this is framed by a general "memento mori" and a particular coat of arms). But this sequence may well be incomplete or not entirely reflect the intended purpose: for instance, "Vanity" may also be a depiction of "Luxuria", etc.
Question of attribution.
The attribution of the work has been disputed. In 1890, Wilhelm von Bode bought it in Florence, Italy, as a Memling, but as early as 1892, he attributed it to Memling's contemporary, Simon Marmion. This attribution was kept by some specialists, while several others – such as Hugo von Tschudi, Georges Hulin de Loo, and Max J. Friedlander – maintained that it was indeed a Memling; of the late period and of very high quality as far as Friedlander was concerned. The debate later shifted on the question of authenticity: it was questioned if it was a painting by Memling himself, or rather by an assistant, a follower, or an imitator. The question has been settled since 1994, when thorough examination showed that it was indeed a genuine work by Hans Memling himself.
Question of destination.
The destination of the work has been just as disputed. The coat of arms had been attributed to several Italian families, until Hulin de Loo identified it as the Loiani family crest. The work may have been commissioned by Giovanni d′Antonio Loiano, from Bologna, who had married a Flemish woman. It remains unresolved if the work was as it is now, i.e. a triptych, or if a recto-verso panel has been lost and the work had originally been a polyptych. This hypothesis in turn raises the question of the painterly subjects on either side of the lost panel. Moreover, as it could be closed (as a triptych), or folded (as a polyptych), there is no certainty as to the order in which the paintings were shown in either state. "Earthly Vanity and Divine Salvation" was probably used for private devotion, as a domestic altarpiece that could also be carried with its owner.
Question of iconography.
The iconographic program of "Earthly Vanity and Divine Salvation" is complex, although not impenetrably so, hence the title given to the work. The proponents of the theory that a fourth recto-verso panel is missing suggest that it could have shown the Virgin Mary (responding to her son depicted as a "Salvator Mundi" but also with attributes of a "Christ in Majesty", such as the crown) on one side, and Adam on the other (responding to Eve, depicted as the allegorical figure of "Vanity"). The purposes of "Death", "Hell", "Memento mori", and the coat of arms, are quite clear, although their position is not. "Vanity" (which may also represent "Luxuria") and "Death" share aesthetic and thematic parallels, not least in the very prominent genital area, a fact that has prompted the tenants of the triptych hypothesis to dismiss the idea that "Vanity/Luxuria" should have been paired with another painting instead. On the other hand, the probable pairing of "Christ" with "Hell" is theologically untenable; as in Memling’s own "Last Judgment", depictions of Hell are generally paired with depictions of Heaven.
Satan's face on the belly () has been noticed by art historians, as has Vanity's/Luxuria's eroticism.
Possible pairings.
The following pairings have been suggested as being the most plausible:
As a triptych:
As a polyptych:
In both cases, only "Vanity" and "Death" appear together on the same side, while "Hell" and "Christ", and "Hell" and "Death", and even "Memento mori" and "Coat of arms" appear once on the same side, and once on opposite sides.
