| Reverse description | The central field features an abstract artistic composition referencing Hamilton's discovery of quaternion algebra, with flowing cursive mathematical notation and formulae encircling a bold inverted triangle — an allusion to the quaternion operator nabla (del). The surrounding raised border legend reads SIR WILLIAM ROWAN HAMILTON 1805-1865 along the upper arc, and 10 EURO along the lower arc, commemorating the bicentenary of the Irish mathematician's birth. |
