At first sight it is a surprise that it’s. [definitional]
At first sight it is a surprise that it’s made of bronze at all, since neither copper nor tin – both of which are needed to make bronze – are found on Crete. Both came from much further afield, with the copper coming from Cyprus – the very name of which means the ‘copper island’ – or from the eastern Mediterranean coast.
