In many cultures rainbows are a symbol of hope. They appear sometimes as perfect arcs, often during a rainstorm, when the sun shines onto water droplets, shattering its white light into an array of brilliant colours. Everyone loves a rainbow.  It produces that frisson of excitement and wonder which is not dissimilar to watching fireworks explode in the sky.  There are many superstitions connected with this phenomenon – the most common being that there is a pot of gold where the rainbow ends.  There have been popular songs such as:  “Somewhere over the rainbow” about the yearning for freedom such as that which bluebirds enjoy when they soar over the clouds.

The earliest story about a rainbow is the one in the first book of the Bible, Genesis 9: 13 – 17, when God, after causing a flood to wash away humanity’s corruption, put the rainbow in the sky  as the sign of his promise to Noah and his family with the animals in the ark that he would never again destroy the earth with flood. The rainbow became  a symbol of hope, a new day, and a divine promise. And so it has been viewed through the centuries.

However in the 20th century  the rainbow has been adopted by movements of social change. In the 1960s a rainbow flag was used at peace marches in Europe and also at demonstrations against nuclear weapons, symbolising a desire for peace. In the 1970s, Gilbert Baker designed the rainbow flag for the LGBT community, and the rainbow flag became a symbol of pride, with the different colours representing ‘diversity’ in the gay community. In the 1990s Archbishop Desmond Tutu coined the term ‘rainbow nation’ to describe South Africa, and this term was used by Nelson Mandela following the 1994 elections, when it became a symbol of reconciliation and unity.

Now in the 21st-century, with the world is living with the catastrophe and the suffering caused worldwide by coronavirus, in the UK we have reverted to using this age-old symbol once again.  Houses adorned with rainbows have become a common sight during lockdown, often in the form of children’s drawings put up in windows.  Rainbows have become a symbol of support for the NHS and public gratitude to all those who are working with the sick and the dying in our communities. It is aligned with the government exhortation to save the NHS.

During 2020 the rainbow with its arc of translucent colours has become once again a symbol of fervent hope that the pandemic will end. It won’t be tomorrow but it may be next year. It is almost inevitable that we will be entering another third lockdown in the new year. And no one knows how long it will last – but many of us suspect it will be some months before things improve with the rollout of the vaccine.

Our optimism is still in check. The future is uncertain. Let’s hope we can see the light and trust in the promise at the end of the rainbow, when the dark clouds finally disappear.
