1984  "...one of the finest draughtsman in the country". Hilary Pyle, Irish Times, 27th February. 

1988  "Spare, even gaunt, these unbending works are not for casual inspection but rather demand and deserve the contemplation and concentration that has gone into their making". Desmond McAvock, Irish Times, 20th April.

1988  "...his drawings are a fascination for me". Hilary Pyle, Cork Examiner, 19th April.

1988  "Walsh is technically adroit and rigorously methodical, and the motifs have a curious resonant power..." Aidan Dunne, Sunday Tribune, 1st May.

1989  "Walsh's 'Arena', which marks both a moment of continuing evolution and a decisive change in his work, shows him to be in the mainstream of a diverse and thriving tradition, and it perpetuates the living vitality of non-objective art through its questing, interrogative nature". Aidan Dunne, 'The Arena Paintings 1987-1989', (catologue), Limerick City Gallery of Art.

1995  "Samuel Walsh has made difficult choices in his art project. The work presents both philosophical conviction, a density that has worked through to the point where a hard-earned starkness informs the image. His agenda now includes the harmonics of emotional order. The meeting, a timely risk, promises well". Brian Coates, Irish Times, 27th April.

1997  "This is unusual and highly accomplished work, in a catagory all of its own". Allanah Hopkin, Sunday Times, 23rd March.

1997 "His own drawing has an interesting quasi-architectural character, and his abstract painting has developed in qulaity and authority". Dorothy Walker, Modern Art in Ireland, Lilliput Press.

1999  " Walsh's work usually brings to mind concepts of rationality, control and precision. But the idea of chaos is an essential component of his painterly world". Aidan Dunne, Irish Times, 5th May.

1999  "The paint is applied with a palette knife, energetically swirled and scraped onto the background surface or rendered in little dabs or smears to construct the objects themselves, which creates a rich surface texture and yet another dimension." Marianne Hartigan, Sunday Tribune, 9th May.

2000  "His particular vision of the world continues to prioritise the marginal over the central. It persistently retrieves for consideration and pictorial transformation what might otherwise be overlooked. It is at heart an examination as well as an exaltation of what the artist refers to, with disarming simplicity, as 'the edges and ends of things'." Caoimhin MacGiolla Léith, 'Drawings 1982-2000', (catalogue), University College Cork.

2001  "Spend time with this work and subtle contexts begin to reveal themselves." Mark Ewart, Irish Times, 12th January. 

2003  "Colour itself has also varied across the series, bold and unequivocal primaries in some paintings, muted and neutral in others. The latter are not arrived at by pure mixes but through the layering of softer tones over pure hues; with encaustic on occasion lending texture and sunstance to the surface." "Against the rich hues and their muted cousins we find the pervasive, menacing presence of black, which Walsh treats as a colour itself, rather than a tone." Mark Ewart, 'Ambit', (catalogue), Limerick City Gallery of Art.

2003  "The resolution of each finished image is like a wary truce that doesn't rule out further hostilities: obviously it is abstract art that allows a range of applications to the world beyond the confines of the picture." Aidan Dunne, Irish Times, 23rd January.

2003  "But the overall effect is of balance, a kind of inevitable status quo being reached in the battle for dominance between the planes of colour." Alannah Hopkin, Irish Examiner, 24th January.

2003  "While the works relate to his earlier, precise, almost architectural work - these paintings have a new vibrancy, a tension and energy and often dramatic colour contrasts." Marianne Hartigan, Sunday Tribune, 4th May.

2004  "The colours are as bold as the shapes themselves..." "The dialogue between the two provides a visual tension, but there is a beguiling stillness at the heart of Walsh's work." Mark Ewart, Irish Times, 3rd March.

2006  "Samuel Walsh has established himself as one of the country's leading exponents of abstract art..." Róisín Kennedy, National Self-Portrait Collection of Ireland, Volume 2, University of Limerick Press.

2007  "The strong washes in the Testa and Phidias series create an almost dappled effect that contrasts with the bold black lines that traverse them. Walsh succeeds in reinvigorating a classical subject by making it his own." Catherine Leen, Sunday Times, 25th march. 

2007  "He is not a man for careless use of colour; it is employed with intelligence". "Walsh is an ethical painter in this Kierkegaarden sense, that is, his aesthetic judgements flow from an ethical context". John Daly, 'Selected Work', Hillsboro Fine Art, Dublin. 

2007  "Your painting is fresh and independent, and reflects a true originality. It is the originality, independence, and technical excellence of your work that has moved us to invite you here." Invitation letter to take up an artists' residency from the Josef & Anni Albers Foundation, Bethany, Connecticut, USA, September.

2008  "The highly visual text has proovided artists with with ample inspiration from Botticilli to Blake, from Doré to Delacroix and Dali. And now Samuel Walsh has joined their esteemed company in his version of The Divine Comedy." Karen Normoyle-Haugh, Circa visual art magazine, Spring, 2008.

2009  "One of the most beautiful is Baetica X, by Samuel Walsh, where delicate pinks and greens delineate a three-tiered landscape, and a network of dark lines makes a sketchy leap into the sky". Gerry McCarthy, Sunday Times, 7th June.
