Immram

An immram (/ˈɪmrəm/; plural immrama; Irish:iomramh, pronounced [ˈʊmˠɾˠəw], voyage) is a class of Old Irish tales concerning a hero's sea journey to the Otherworld (see Tír na nÓg and Mag Mell). Written in the Christian era and essentially Christian in aspect, they preserve elements of Irish mythology.
