Photographer's Note

Another picture from the "empty signs" series.

PS. There has been a discussion about the purpose of these signs in the course of which their mystery was finally demystify. Enia has found out that they are used for measuring the rowing speed.

At the web page Floating Down The River it is explained as follows:

In applying the speed limit the authorities have chosen to measure the speed ‘over the bed of the river’ rather than ‘through the water’. This gives rise to two problems. It doesn’t take into account the current, which can be considerable, and it doesn’t recognise that logs (speed indicators) fitted to boats measure speed through the water. There is no mechanism on a boat for measuring its speed over the ground unless it has GPS fitted.

This to a certain extent has been recognised by the EA who have installed, in the following locations, red triangles on black and white poles set on the side of the riverbank at distances such that it should take one minute to travel between them at the speed limit.

If it takes less than a minute you are speeding! This helps to correlate your log, but beware, River Inspectors on the EA launches have Radar guns.


I think, however, that the knowledge about the practical purpose of these signs doesn't abolish their obscure symbolic meaning and aesthetic impact.
