This is a series on earthly sky, portrayed as seen from both the lower and the upper edge.
Each diptych in the series functions as a mirror where the two instances of the same sky partially interfere and complete one another. This way, the image of the sky is recreated as a whole, but on the vertical axis that is not naturally accessible to the human eye.

While exposing our limits, the visual metaphor also attempts to institute us as part in something bigger: the great vertical, the axis that keeps our world placed in the universe.
