Une proposition.

I guess that 'croisement d'oeuvres' is linked to drawing comparisons. In French, it means that comparisons are formal and/or subjectives.
I hope it'll help, a bit hard to translate exactly in English.

this is how I would see it - "as you can see the Marian blue is just as prominent in this 15th century piece as in the later 16thcentury representation etc. etc."..

This would be another way of saying it - I realise we shouldn't be putting suggestions in the clarification section, so before they are all removed....

To elongate perspectives; gain height; escape the restrictions of different floors; capture points of view; arrange presentation; establish affinities between works; unify the whole museum around the large Khmer room and around a patio facing skywards; to balance the entire building by means of two large stairs placed symmetrically in the rotunda which acts as a hall on the ground floor: these are expressions of our desire to create accessible connections. One is aware that, when it comes to Asian art, the positioning of the objects (sculptures, paintings, ceramics), the area they inhabit, the air that surrounds them, is of utmost importance. To this end, we have given thought to everything: in the open or under glass, separation and appositions, repetitions and free associations. Sometimes, it is the sculpture collections which have been arranged, sometimes different alignments: always in the spirit of aeration: in constellations and in more ordered layouts.

Opening in stages through the spring and summer, and timed to coincide with the ongoing restoration of the Guggenheim’s most iconic space, its Frank Lloyd Wright building, The Shapes of Space will explore various ways in which artists from the early modern period through the present have conceived of and represented space—from spiritual or utopian visions of space, to investigations of the built space, to the activation of a social space that elicits the viewer’s participation. Drawn from the Guggenheim’s extensive permanent collection, The Shapes of Space will feature a number of major recent acquisitions, including large-scale, immersive installations by Pipilotti Rist, Rirkrit Tiravanija, and Piotr Uklanski. Non-chronological and experimental in approach, the exhibition will present unexpected juxtapositions and identify surprising affinities between works of various time periods.

Not chronological, geographically-bound or thematic, Constructing a Poetic Universe focuses instead on provisional and improvisational relationships that surface in the Halle collection. The eccentric survey of a private collection encourages unexpected dialogues between works beyond the chronological, cultural and contextual. Affinities between works—visual, conceptual, ideological, historical, or forced by proximity—provoke both resonance and tension. The ever-expanding web of associations created by the works in the Halle collection has the ability to create new fictions, new universes of Borgesian dimensions.
