The King’s Threshold was first played October 7th, 1903, in the Molesworth Hall, Dublin, by the Irish National Theatre Society, and with the following cast:
| Seanchan | Frank Fay |
| King Guaire | P. Kelly |
| Lord High Chamberlain | Seumus O’Sullivan |
| Soldier | William Conroy |
| Monk | S. Sheridan-Neill |
| Mayor | William Fay |
| A Cripple | Patrick Colum |
| A Court Lady | Honor Lavelle |
| Another Court Lady | Dora Melville |
| A Princess | Sara Algood |
| Another Princess | Dora Gunning |
| Fedelm | Maire ni Shiubhlaigh |
| A Servant | P. MacShiubhlaigh |
| Another Servant | P. Josephs |
| A Pupil | G. Roberts |
| Another Pupil | Cartia MacCormac |
It has been revised a good many times since then, and although the play has not been changed in the radical structure, the parts of the Mayor, Servant, and Cripple are altogether new, and the rest is altered here and there. It was written when our Society was beginning its fight for the recognition of pure art in a community of which one half is buried in the practical affairs of life, and the other half in politics and a propagandist patriotism.
On Baile’s Strand was first played, in a version considerably different from the present, on December 27th, 1904, at the opening of the Abbey Theatre, Dublin, and with the following cast:
| Cuchulain | Frank Fay |
| Conchubar | George Roberts |
| Daire (an old King not now in the play) | G. MacDonald |
| The Blind Man | Seumus O’Sullivan |
| The Fool | William Fay |
| The Young Man | P. MacShiubhlaigh |
The old and young kings were played by the following: R. Nash, A. Power, U. Wright, E. Keegan, Emma Vernon, Dora Gunning, Sara Algood. It was necessary to put women into men’s parts owing to the smallness of our company at that time.
The play was revived by the National Theatre Society, Ltd., in a somewhat altered version at Oxford, Cambridge, and London a few months later. I then entirely rewrote it up to the entrance of the Young Man, and changed it a good deal from that on to the end, and this new version was played at the Abbey Theatre for the first time in April, 1906.
The first version of The Shadowy Waters was first performed on January 14th, 1904, in the Molesworth Hall, Dublin, with the following players in the principal parts:
| Forgael | Frank Fay |
| Aibric | Seumus O’Sullivan |
| Dectora | Maire ni Shiubhlaigh |
