Refulgent light in the Sonian Forest

Jan Brueghel the Elder and Peter Paul Rubens, The Vision of Saint Hubert, 1617-20

I have been reading Woodland Imagery in Northern Art c. 1500-1800 by Leopoldine van Hogendorp Prosperetti, published with beautiful illustrations by Lund Humphries two years ago. It is written in a slightly eccentric, charmingly old-fashioned and accessible style with short chapters covering various artists and genres of sylvan imagery, from van Eyck to Rubens. The iconography of trees is linked to an interesting range of sources in Latin vocabulary, religious traditions, pastoral poetry and the wider influences of politics, patrons and print technology. A chapter on Dürer includes sketches made in Nuremberg and a linden tree on the bastion of the castle that I mentioned here last month, I could discuss this or other interesting topics I found interesting, but I'll focus here on a painting by the artist Leopoldine Prosperetti has specialised in, Jan Brueghel the Elder. 

The Vision of Saint Hubert (1617-20), now in the Prado, was one of Brueghel's collaborations with Rubens. It shows one of the two famous saints who had a conversion experience while out hunting - he is not to be confused with Saint Eustace, the Roman general who features in the Canterbury Cathedral wall hanging and Russell Hoban's Riddley Walker. Hubert (c. 656-757) was the 'Apostle of the Ardennes' and the two Flemish artists may have chosen this subject to please their patrons, Archduke Albert and Archduchess Isabella. This quote is from Prosperetti's chapter that focuses on woodland imagery associated with the Sonian Forest on the edge of Brussels. The passage includes two words you don't often come across: reflexy-const and talud.

The finishing touches in these pictorial settings would be passages of light that enhanced the scenery. The term in art theory is reflexy const (the art of reverberated light), which assigns to bounced-off sunlight the function of bringing scenery to life. In classical paintings, these areas of luminosity appeared on the smooth facets of grottoes, rockeries or ruins, to scatter the light to neighboring surfaces. In a sylvan setting, where there would be no resplendent surfaces other than leaves, painters would focus their attention on patches of sand, which, with the right amount of sunlight falling through the gaps in foliage or the opening of a clearing, would create pools of refulgent light. One such opportunity is provided by the talud, the sloping shoulder of a sunken path that is typical of the traveled road in age-old forests. An example of this curious land formation rises above Saint Hubert, bearing a slanted oak barely holding on to the sandy soil. It pairs visually with an illuminated sandy patch below the group of oaks on the other side of the path, which serves as a platform for the stag. 

The deer's antlers and the broken branch on the highlighted patch of ground form another pair: forked forms which Prosperetti finds frequently in Brueghel's paintings and which suggest the forking path of a decision. The cross which Hubert will choose is hovering above the antlers, so small you probably can't see it on your screen... Prosperetti suggests that the hart (cf. heart) at the centre of the forest was like the ducal court at the heart of the Duchy. Isabella's grandfather Charles V, whose hunts in the Sonian Forest are depicted in tapestries that now hang in the Louvre, chose as his motto a verse from the Psalms: 'As the hart panteth after the water brooks, So panteth my soul after thee, O God!'
