It must have been on Synge’s second visit to the Aran Islands that he had the experience out of which was wrought what many believe to be his greatest play. The scene of "Riders to the Sea" is
laid in a cottage on Inishmaan, the middle and most interesting island of the Aran group. While Synge was on Inishmaan, the story came to him of a man whose body had been washed up on the far
away coast of Donegal, and who, by reason of certain peculiarities of dress, was suspected to be from the island. In due course, he was recognised as a native of Inishmaan, in exactly the
manner described in the play, and perhaps one of the most poignantly vivid passages in Synge’s book on "The Aran Islands" relates the incident of his burial. The other element in the story
which Synge introduces into the play is equally true. Many tales of "second sight" are to be heard among Celtic races. In fact, they are so common as to arouse little or no wonder in the minds
of the people. It is just such a tale, which there seems no valid reason for doubting, that Synge heard, and that gave the title, "Riders to the Sea", to his play.
