Read the text below and answer Questions.WHY DO CLOCKS GO CLOCKWISE The simple answer is that clocks always go clockwise!If the clock’s hands moved in the opposite direction(to what we are used to), it would still be called ’clockwise’ , of course!But, seriously, why do the hands move from left to right at the topGenerally, the answer given is that clocks were invented in the northern hemisphere where the sun rises in the east, travels round to the south, and sets to the west. The shadow on a typical domestic sundial in olden times would move from left to right. So, the answer is completely logical. Or is it If we go back to early clocks, because of their sheer size and cost, there was generally only one turret clock in a town, usually placed high on a tower for all to see and frequently accompanied by a bell that could be heard when the clock face was not visible. If we go back in time to before mechanical clocks, even if people had a sundial at home, they needed a large public sundial that could be read from a distance when they were out. Sundials were therefore placed high on a wall in the town. This is where the explanation above about clockwise movement no longer rings true:for sundials on vertical walls have to have their hours arranged in an anti-clockwise progression. As vertical sundials would have been the predecessors of clock towers, one wonders why a right to left movement didn’t become the standard. An old vertical sundial can still be seen in Queen’s College, Cambridge, England. Not only does it go ’anticlockwise’ but strangely(for us)the number ’I’ is at the bottom rather than the top.

There is a clock Painted in fresco in a Cathedral in Florence that is peculiar in several ways. We are used to clocks with twelve hours on the dial but this one has twenty-four and the twenty-fourth hour does not signify midnight but the hour of sunset(a system that survived until the eighteenth century apparently);furthermore, the layout of the numbers has ’I’ at the bottom, although of course Ⅻ is at the top, and it goes anticlockwise!This clock is not unique, however.
