An iconic Irish painting has returned to Ireland after being away for 35 years. The painting of 'The Battle of Clontarf' by Hugh Frazer was on display at the Isaac Arts Centre in Hawaii.

Prior to that, it was in the personal collection of American philanthropist George Isaac. Mr. Isaac, who has Irish ancestry, purchased the painting from a private collection in Ireland 35 years ago.

In the 1990s he donated over 20 paintings to the Isaac Art Centre, then being constructed and financed by him.

It is featured in many books on Brian Boru - and depicts the High King looking out over the battlefield stretching into the distance, with Howth in the background.

The 3x2 metre painting will go on display at the Casino Marino in Dublin next month for free.

Emer Finnan is managing-director of Kildare Partners, who now own the piece. "It's such a distinctive image of Irish history and it's great to have it back in Ireland" she said.

A series of events is being held around the country this April to commemorate the Millennium of the Battle of Clontarf.

Collette Gill, chair of the Clontarf 2014 committee, has been working on this project behind the scenes for the last few months.

"Our committee is delighted to have this iconic painting of the Battle of Clontarf back here in Ireland for the 2014 millennium commemoration and the Casino at Marino is such a fitting place to show this wonderful painting" she said.

"The elevated site of the Casino would have overlooked the battle 1,000 years ago" she added.
