It seems appropriate to reflect today, it being St Patrick’s Day, on Trollope as an Irish writer.
He went to Ireland as an unsuccessful clerk of the Post Office. He was in the proverbial last chance saloon with his employer. Yet something about the place captivated him and he turned his life around. He met and married Rose Heseltine. He took up fox-hunting (not a pass-time with which I sympathise but I can still enjoy the hunting passages in his books that were doubtless inspired by his experiences in the field). And he began to write novels which, with each one, showed growing skill and maturity.
He has left us several novels that are specifically Irish: The Macdermots of Ballycloran, The Kellys and the O’Kellys, Castle Richmond, An Eye For An Eye and The Landleaguers. In addition there are two of the political novels, Phineas Finn and Phineas Redux which feature the eponymous Irish Member of Parliament and address Irish political questions (albeit somewhat obliquely).
On the strength of these I think he may unequivocally be included in the pantheon of Irish writers.
For a thorough understanding of how Trollope was influenced by Ireland in his writing, you can consult the fascinating study Writing The Frontier: Anthony Trollope Between Britain and Ireland by John McCourt, published by Oxford University Press.
