Where would we be without arrows to guide us to our destinations, to lead us
through the maze of corridors in hospitals, universities and public
buildings, not to mention to WCs when nature calls? Arrows also help to keep
us safe, to ensure that we keep to the correct side of the road and avoid us
colliding with all the other travellers going about their daily business.
But there is one arrow missing in the photos below: the arrow shot by Cupid, the Roman god of love, to inspire desire.
