Sir, – While we may not know what happened at Newgrange 5,000 year ago, it would seem reasonable to surmise that people gathered, possibly in bright clothing, with drums and other instruments to share joy at the incipient lengthening of the light – as people do today around the globe. Unlike Kevin Nolan (Letters, December 24th), I welcome that joy. – Yours, etc,
Dr GERALDINE MOANE,
Dublin 12.
