At the entrance to For Want of (not) Measuring, a contemporary art exhibition, visitors gape at a skull. It is of a bird, but its scale suggests something other. The sculpture rises 2.8 metres above the floor of Spazju Kreattiv in Valletta and balances improbably on its beak atop a column. From some angles, it resembles a fossil; from others, a warning. The work is by Maltese artist Prof. Trevor Borg, titled In the Balance.
