The highest tides occur with the coming of the full and new moons, and many believe these natural events coincide with a rise in madness, hence the term ‘lunacy‘. In days gone by, coastal people used the regular cycle of tides to mark the passage of time instead of the clock. The tide is frequently represented in literature as something unstoppable, which cannot be harnessed by humans. As the Scottish poet Robert Burns observed: “Nae man can tether time or tide“. When our circumstances change, the tide is said to be turning, and we often speak of moving ‘with’ or ‘against’ the tide.
