The Lintel Sculpture is spread in monumental proportions above the exterior of the Library’s front doors. Comprising over 3 tonnes of copper, the sculpture was transported in 3 trucks to the Library, where the pieces were welded together on site. The work is based on allegorical symbols based on ancient Sumerian and Akkadian seals dating back to 3000 BC. At the centre is the winged sun, symbolising enlightenment and inspired truth. On the right are spear-like tree branches representing the source root and continuous growth of knowledge. On the left is the curved ark of knowledge, referring to the Library’s place in collective memory and preservation of intellectual endeavour.
