DINDSHENCHAS

or Dinnsheanchas, (Gaelic: Lore of Places), studies in Gaelic prose and verse of the etymology and history of place-names in Irelande.g., of streams, raths (strongholds of ancient Irish chiefs), mounds, and rocks. These studies were preserved in variant forms in monastic manuscripts dating from as early as the 12th century. The Dindshenchas contain much pre-Christian mythology, especially stories of gods and fairies. The most famous collection is the Dindshenchas ascribed to Amhairgin mac Amhalgaidh, a poet to King Diarmaid in the 6th century. It describes the naming of more than 200 locations and was an important source for Irish poets, who were expected to be familiar with the lore of each area.
