The "Visio Tnugdali" with its interest in the topography of the afterlife is situated in a broad Irish tradition of fantastical tales about otherworldly voyages, called "immram", as well as in a tradition of Christian afterlife visions, itself influenced by pre-Christian notions of the afterlife. Other important texts from this tradition include the Irish "Fís Adamnáin" ("The Vision of Adamnán") and Latin texts such as the "Visio Pauli" ("Vision of Paul"), "Visio Thurkilli", "Visio Godeschalci", and the "Tractatus de Purgatorio Sancti Patricii" (an account of a visit to Saint Patrick's Purgatory).
