Hiraeth is a Welsh word with no precise English synonym or  equivalent. I take it to mean a form of spiritual desolation formed by a nostalgia for a home we never had. How life was before the fall from grace and into the realm of mortality. A pre-lapsarian sense of the beauty of the garden of Eden: a time out of time, and a place out of place. 

Hedd Wyn the shepherd poet who wrote in Welsh explored the implications associated with Hiraeth. This form of spiritual nostalgia is not restricted to Wales or Welsh people. I think it describes a widespread sense of spiritual homelessness and desolation common in the 21st century. 

Rhyfel

Gwae fi fy myw mewn oes mor ddreng
A Duw ar drai ar orwel pell;
O'i ôl mae dyn, yn deyrn a gwreng,
Yn codi ei awdurdod hell.

Pan deimlodd fyned ymaith Dduw
Cyfododd gledd i ladd ei frawd;
Mae swn yr ymladd ar ein clyw,
A'i gysgod ar fythynnod tlawd.

Mae'r hen delynau genid gynt
Ynghrog ar gangau'r helyg draw,
A gwaedd y bechgyn lond y gwynt,
A'u gwaed yn gymysg efo'r glad.

Hedd Wyn 

War

Woe that I live in bitter days,
As God is setting like a sun
And in his place, as lord and slave,
Man raises forth his heinous throne.

When he thought God was gone at last
He put his brother to the sword.
Now death is roaring in our ears,
Shadowing the shanties of the poor.

The old and silenced harps are hung
On yonder willow trees again.
The bawl of boys is on the wind.
Their blood is blended in the rain.

Hedd Wyn. 1887-1917. Killed in action. Ypres
