Neil Macgregor did a marvellous History of the World in a hundred objects recently. Well a similar idea is happening in Ireland, the three links below are the first three.

Flint macehead, 3300-2800 BC
"This ceremonial macehead, found beneath the eastern chamber tomb at the great passage tomb at Knowth, in the Boyne Valley, is one of the finest works of art to have survived from Neolithic Europe. The unknown artist took a piece of very hard pale-grey flint, flecked with patches of brown, and carved each of its six surfaces with diamond shapes and swirling spirals. At the front they seem to form a human face, with the shaft hole as a gaping mouth.".....

Ceremonial axe 3600 years old
"Even now, its sheen and colour are magnetically alluring, the jade green surface, mottled with darker veins and glimmers of light, polished to a high sheen. The shape is beautifully balanced between sharp edges and elegant curves. It was once thought that it must have come from China. But if it looks exotic and mysterious now, 5,000 years ago in Ireland it would have seemed astonishing."

Neolithic bowl, c 3500 BC
"The bowl is simple enough, very dark with burnished surfaces and relatively crude lattice-pattern decorations. It was probably used for drinking and similar vessels have been found elsewhere in Ireland.
Yet, because of the context in which it was found, this everyday object is extraordinarily eloquent. It tells us a great deal about the lives of some of the earliest Irish farmers."
