Bartholomeus Breenbergh: CIMON UND IPHIGENIA
1638. Öl auf Eichenholz. 60,3 x 53 cm
Mit einem Gutachten von Max J. Friedländer, Berlin, vom 28. November 1926, als „reizvolles, echt signiertes Werk von B. Breenbergh“ (im Original). 

EUR 30.000 – 50.000
US$ 33,500 – 55,800


Amor raubt keineswegs nur den Verstand. „Erwacher des schlafenden Geistes“, so nennt ihn Boccaccio in seinem ersten Gesang des V. Decamerone. Der Dichter veranschaulicht die „heilige Wirkung der Liebe“ anhand eines Exempels: Gales, gutaussehender Sohn eines Edelmannes, war so ungehobelt und unerzogen, daß die Menschen Zyperns ihn Cimone, gleichbedeutend mit Rohling, nannten. Cimones Dummheit ärgerte seinen Vater so arg, daß er den Jungen in die Wildnis schickte. Fernab der Zivilisation lebte er zufrieden bis er auf ein schlafendes Mädchen stieß, Iphigenie.

Ihre Schönheit verwandelt ihn vollkommen. Zum Erstaunen aller kleidet sich der einstige Dummkopf in hübschen Gewändern, knüpft tiefe Beziehungen, erlernt Musik, studiert Philosophie, dichtet und macht seiner Angebeteten den Hof. Der Augenblick des Verliebens ließ ihn schlagartig vom „Wilden“ zu einem besseren Menschen werden, und zum Schluß macht er die Schöne zu seiner glücklichen Frau.

Das Gemälde fällt in die Zeit der Wiederentdeckung antiker Literaturstoffe. Die mythologische „Novella“ Boccaccios begeisterte viele Zeitgenossen Breenberghs und in der Umsetzung war es sein absolutes Lieblingssujet - zwischen 1633 und 1647 hat er diese Szene mindestens siebenmal ganz unterschiedlich variiert.

In der Mitte unserer Fassung liegt Iphigenie, unbekümmert vermittelt sie den Eindruck sich zugleich hilflos hinzugeben und den unbehelligt beobachtenden Cimon lautlos verführen zu wollen. Wie in der literarischen Vorlage ist der Sohn vor Verzückung über den Anblick kontemplativ über seinen Stock gebeugt. Die Gruppe schlafender Frauen ist von besonders feinmalerischer Qualität und Breenbergh verleiht ihnen etwas sehr zartes, fast zerbrechliches. Subtil gelingt es ihm, mit dem sich über Iphigenie erstreckenden, aber abgebrochenen Torbogen der Ruine die sich anbahnende Verbindung zwischen dem zukünftigen Paar anzudeuten. Die lockere Behandlung der von Licht durchsetzten Landschaft ist von jener „zarten Duftigkeit“ (Wolfgang Stechow 1930), die typisch ist für jene Phase Breenberghs, in der nicht zufällig auch seine hochwertigsten Radierungen entstanden.

Meister von Frankfurt: MARIA MIT DEM KINDE
Um 1510. Öl auf Eichenholz. 36,6 x 28,5 cm

EUR 10.000 – 15.000
US$ 11,200 – 16,700


Wegen des Vergleichsbeispiels in Brüssel und ähnlicher Tafeln im Musée des Beaux-Arts in Poitiers sieht Didier Martens einen klaren Bezug zu dem Meister der Magdalenen-Legende. Peter van den Brink sieht hingegen in der Tafel – sowohl wegen der Gestaltung der Komposition als auch der Figuren – zweifelsfrei ein typisches Beispiel des Meisters von Frankfurt.

Lives without imagery – congenital aphantasia

by Adam Zeman, Michaela Dewar, and Sergio Della Sala
Cortex, Available online 3 June 2015
,
doi:10.1016/j.cortex.2015.05.019

1.  Introduction
Visual imagery is, for most of us, a conspicuous ingredient of everyday experience, playing a prominent role in memory, daydreaming and creativity. Galton, who pioneered the quantitative study of visual imagery with his famous ‘breakfast-table survey’, reported a wide variation in its subjective vividness  (Galton, 1880). Indeed, some participants described ‘no power of visualising’. This phenomenon has received little attention since, though Faw reported that 2.1-2.7% of 2,500 participants ‘claim no visual imagination’ (Faw, 2009).

The experience of voluntary imagery is associated with activity in fronto-parietal ‘executive’ systems and in posterior brain regions which together enable us to generate images on the basis of our stored knowledge of appearances  (Bartolomeo, 2008). The relative contributions of lower and higher order visual regions to the experience of visual imagery are debated (Bartolomeo, 2008). Clinical reports suggest the existence of two major types of neurogenic visual imagery impairment: i) visual memory disorders, causing both visual agnosia and imagery loss, and ii) ‘imagery generation’ deficits selectively disabling imagery (Farah, 1984).

In 2010 we reported a particularly ‘pure’ case of imagery generation disorder, in a 65 year old man who became unable to summon images to the mind’s eye after coronary angioplasty (Zeman et al., 2010). Following a popular description of our paper  (Zimmer, 2010), we were contacted by over twenty individuals who recognised themselves in the article’s account of ‘blind imagination’, with the important difference that their imagery impairment had been lifelong. Here we describe the features of their condition, elicited by a questionnaire, and suggest a name – aphantasia - for this poorly recognised phenomenon.

2.  Results
21 individuals contacted us because of their lifelong reduction of visual imagery. We explored the features of their condition with a questionnaire devised for the purpose and the Vividness of Visual Imagery Questionnaire  (VVIQ) (Marks, 1973)  (see supplementary material  for further details). Participants typically became aware of their condition in their teens or twenties when,  through conversation or reading,  they realised that most people who ‘saw things in the mind’s eye’, unlike our participants, enjoyed a quasi-visual experience. 19/21 were male. 5/21 reported affected relatives. 10/21 told us that all modalities of imagery were affected.  Our participants rating of imagery vividness was significantly lower than that of 121 controls (p<.001,  Mann  Whitney  U test  –  see Figure 1). Despite their substantial (9/21) or complete (12/21) deficit in voluntary visual imagery,  as judged by the VVIQ, the majority of participants described involuntary imagery. This could occur during wakefulness, usually in the  form of  ‘flashes’ (10/21)  and/or during dreams (17/21). Within  a  group of participants who reported no imagery while completing the  VVIQ, 10/11 reported involuntary imagery during wakefulness and/or dreams, confirming a significant dissociation between voluntary and involuntary imagery (p<.01,  McNemar Test).  Participants  described a varied but modest effect on mood and relationships.  14/21  participants reported difficulties with autobiographical memory. The same number  identified compensatory strengths in verbal, mathematical and logical domains. Their successful performance in a task that would normally elicit imagery  –  ‘count how many windows there are in your house or apartment’  -was achieved by drawing on what participants described as ‘knowledge’, ‘memory’ and ‘subvisual’ models.

3.  Discussion
φαντασία, phantasia, is the classical Greek term for imagination, defined by Aristotle as the ‘faculty/power by which a  phantasma  [image or mental representation] is presented to us’ (Aristotle, 1968).  We propose the use of the term ‘aphantasia’ to refer to a condition of reduced or absent voluntary imagery. Terms used previously in related contexts include ‘defective revisualisation’  (Botez, Olivier, Vezina, Botez, & Kaufman, 1985)  and ‘visual irreminiscence’ (Nielsen, 1946).

Sceptics could claim that aphantasia is itself a mere fantasy: describing our inner lives is difficult and undoubtedly liable to error (Hurlburt & Schwitzgebel, 2007). We suspect, however, that aphantasia will prove to be a variant of neuropsychological functioning akin to synaesthesia (Barnett & Newell, 2008) and to congenital prosopagnosia (Gruter, Gruter, Bell, & Carbon, 2009). Indeed, aphantasia may have some specific relationship to these disorders, as congenital prosopagnosia is associated with unusually low (Gruter et al., 2009), and synaesthesia with unusually high (Barnett & Newell, 2008), VVIQ scores.

The participants described here were self-selected and some of our findings, such as the male predominance, may reflect the  readership of a science magazine like  Discover. There is a need, therefore, for further study in a more representative sample. The existence of lifelong ‘aphantasia’ raises numerous additional questions. How commonly does  congenital aphantasia occur? Existing data suggest a frequency of around 2% but there is no fully reported large scale study. The evidence of familial occurrence should be investigated further. Does  congenital  aphantasia have objective neuropsychological associations? Correlations between  imagery vividness and cognitive functioning have been elusive in the past, but recently developed measures of autobiographical memory  (Levine, Svoboda, Hay, Winocur, & Moscovitch, 2002), imaginative thinking  and ‘visual-object intelligence’  (Blazhenkova & Kozhevnikov, 2010) open up new avenues for exploration. Personality and mood may also be relevant variables.  Are there subtypes of congenital aphantasia? The descriptions given by our participants suggest that in some cases visual memory is preserved even if visual imagery is absent, while others may rely entirely on non-visual representations in memory tasks; the relationship between aphantasia and congenital prosopagnosia also deserves further study. If, as we hypothesise,  the absence or reduction of visual imagery has neural correlates, can we discover these? We are optimistic that modern structural and functional brain imaging may help to answer questions about the nature of visual imagery that were first posed in ancient Greece and first quantified at Sir Francis Galton’s breakfast table over a hundred years ago.
