The architect used this type of half circle nodes in the corridor for constructional reasons and climatic considerations. As far as concern the construction side is the rehabilitation of the ground floor’s nodes of the building to hold the building parts on the first floor of the western corridor represented by the side column and the two nodes. As far as concern the climate aspect, the semicircular contracts work to introduce larger amounts of light to the rooms overlooking the corridor and at the same time provide protection for the rooms from rain and wind.
Through the observations of them, we noticed what the architect did and what the engraver showed through merging the art with architecture considering that the architect used a repetitive changeable pattern of nodes by building five similar nodes but they different in sizes and dimensions and the architect used the principle of unity in the engravings. The architect implemented the palm fan element and framed it from all directions with an geometrical engravings of saw teeth so the weight and balance are different when looking into it and make the split between these nodes similar to the twisted rope.
