Five of the best art shows to see this week in Ireland

Gabhann Dunne looks to water for Dublin while concept artist Leyho picks up on a first WorldWar link


Gabhann Dunne: Crossing the Salt
Limerick City Gallery of Art, Pery Sq, Limerick. Until September 2nd gallery.liumerick.ie
Gabhann Dunne embarked on this body of work while mulling over the proposed re-direction of water from the Shannon to satisfy Dublin's water needs. Over 100 paintings and a wall drawing of the Shannon basin reflect on the nature and experiences of wildlife in this changing environment.

Leah Hewson: Ammo Veil
Hillsboro Fine Art, 49 Parnell Square West, Dublin Until August 11 hillsborofineart.com
Raw gestural marks play against orderly repeat patterns in Leah Hewson's paintings. The gestures seem to aim for or mimic a kind of order too, suggesting a yearning unfulfilled, perhaps. Despite the upbeat colours, it comes as no surprise to learn that Hewson was working through grief having suffered a personal loss.

Signals of Change
Paintings from the Crawford Art Gallery's Great Southern Collection. The Hunt Museum, The Custom House, Rutland St, Limerick Until September 2 huntmuseum.com
Works from the CIE art collection, no less, given to the State and by the State to the Crawford in 2006. They mostly cover a mid-century moment in Irish art, with works by Patrick Collins, Maurice MacGonigal, Daniel O'Neill, Gerard Dillon, Camille Souter, Nano Reid and Arthur Armstrong.

What is Life
Thematic group exhibition. Wexford Arts centre, Cornmarket, Wexford and Wexford County Hall, Carricklawn, Wexford Until September 9th wexfordcoco.ie/arts-and-culture

Leyho (Léo Régeard): Chiens Bleus, Chiens Gris
Olivier Cornet Gallery, 3 Great Denmark St, Parnell Sq, Dublin Until August 24th oliviercornetgallery.com
In conversation, Olivier Cornet and Léo Régeard (who works as a CG artist in film and TV) discovered that both their great grand uncles had served in the first World War – and documented their experiences, Cornet's relation, François Bost, as a photographer, and Régeard's in copious notebook entries. This exhibition plus comic book stems from that connection. Plus, the Graphic Studio's Robert Russell has made three photo intaglios (edition of 25 each) from Bost's original photographs.
