(The British Medical Associationís memorial to those who lost their lives on 7th July 2005, continued...)
Echoing the shape of the dial, the cylindrical plinth is also without a quarter section. This is a reminder of the 'broken pillar' of classical times, symbol of the fallen hero. But the break too serves a purpose. For each year on 7th July precisely,† the shadow cast into it by the corner of the dial, will run along a carved and gilded line, as an annual remembrance of the tragedy.
Similarly the pillar has been devised so that the shadow of its edge, falling diagonally across its base will (at the exact time of the explosion each year) touch a second gilded line. For just that moment, the line will divide light from darkness - life from death - and is a powerful reminder of the tragic events of that terrible day.
