contains motifs elected in other immrama such as: The Voyage of Bran and the Voyage of Saint Brendan. The Island of Joy in paragraph 61 of The Voyage of Bran may have inspired Máel Dúin'''s Island of Uncontrollable Laughter. In both Máel Dúin and the Voyage of Brendan three additional people join the crew. Máel Dúin is joined by his foster brothers; Brendan by three extra monks. In both instances these additions upset the equilibrium of the voyage, and it is when the extra persons are no longer on board, can each voyage be completed. Chapter 11 of Máel Dúin: On the island the crew finds a great fort and tall white pillars. The crew goes into the largest of the houses and finds it empty except for a cat playing on four stone pillars, leaping from one pillar to the next. They see many gold artifacts in the house, including golden necklets. One of the three foster brothers asks to take a golden necklet, to which Máel Dúin replies no. Nevertheless, he steals one anyway. “The cat followed them and leapt through him like a fiery arrow and burns him so that he became ashes.” This is similar to chapter 7 of The Voyage of Brendan when one of the late-coming monks takes a silver brooch despite Brendan's warning and to paragraph 65 of The Voyage of Bran when one of the crew leaps from the ship and turns to ash once he touches dry land. Chapter 18 of Máel Dúin: The crew hears "a great cry and chant" coming from the north-east direction after they sail away from an island. They row for almost two days to find the sound, which is described as sounding like psalms being sung. Eventually, they locate the source, and discover a mountainous island full of colorful birds making loud noises. This event is similar to an event in the "Voyage of Saint Brendan". Brendan and his crew also hear sounds like psalms being sung, and also discover an island full of birds. A major difference between the two events is that in Brendan's tale, these birds are described as praising the Lord directly, whereas in Máel Dúin's tale, the birds are initially described as making psalm like sounds, but ultimately are determined to be just "shouting and speaking loudly". There is less of a religious influence found in the Máel Dúin version
