Oisín ( ), Osian, Ossian ( ), or anglicized as Osheen ( ) was regarded in legend as the greatest poet of Ireland, a warrior of the Fianna in the Ossianic or Fenian Cycle of Irish mythology. He is the demigod son of Fionn mac Cumhaill and of Sadhbh (daughter of Bodb Dearg), and is the narrator of much of the cycle and composition of the poems are attributed to him. Legends His name literally means "young deer" or fawn, and the story is told that his mother, Sadhbh, was turned into a deer by a druid, Fear Doirche (or Fer Doirich). A young hunter named Fionn caught Sadhbh, but did not kill her, and she returned to human form. Fionn gave up hunting and fighting to settle down with Sadhbh, and she was soon pregnant, but Fer Doirich turned her back into a deer and she returned to the wild. Seven years later Fionn found his child, naked, on Benbulbin. Other stories have Oisín meet Fionn for the first time as an adult and contend over a roasting pig before they recognise each other. In Oisín in Tir na nÓg, his most famous echtra or adventure tale, he is visited by a fairy woman called Niamh Chinn Óir (Niamh of the Golden Hair or Head, one of the daughters of Manannán mac Lir, a god of the sea). Niamh's father turned her head into a pig's head because of a prophecy. She tells this to Oisín and informs him she would return to her original form if he marries her. He agrees and they return to Tir na nÓg ("the land of the young", also referred to as Tir Tairngire, "the land of promise") where Oisín becomes king. Their union produces Oisín's famous son, Oscar, and a daughter, Plor na mBan ("Flower of Women"), as well as a second son, Finn. After what seems to him to be three years but in fact was 300 years, Oisín decides to return to Ireland to see his old comrades the Fianna. One tale describes him coming to Ballinskelligs Bay, not far from Ballaghisheen, where he fell off his horse while trying to help move a large stone. Niamh had given him her white horse Embarr and warned him not to dismount because if his feet touched the ground, those 300 years would catch up with him and he would become old
