Táin Bó Flidhais, also known as the Mayo Táin, is a tale from the Ulster Cycle of early Irish literature. It is one of a group of works known as Táin Bó, or "cattle raid" stories, the best known of which is Táin Bó Cúailnge. Táin Bó Flidhais survives in two forms, a short version from the Old Irish period and a longer version found in the 15th century Glenmasan manuscript, which is held in the Advocates Library in Edinburgh. It is believed to be a copy of an earlier manuscript from the 12th century. The early version of Táin Bó Flidhais predates the Táin Bó Cúailnge. It is named for the heroine of the tale, Flidais. Historical setting At the time that these legendary tales relate to (the second half of the Iron Age (approximately AD 50–500) and early Medieval Ireland (approximately 500–800), Ireland was a country divided up into hundreds if not thousands of territories known as tuatha. This tale is likely to relate to incidents around 100 AD before the arrival of people bringing Christian teachings with them. Each tuath had at its head a king. Some kings were higher ranking than others and some, like Medb were the head of an entire province such as Connacht. There was constant battling amongst the kings over territorial boundaries and, as is demonstrated in this story, when one "king triumphed over another, he cut off his victim's head to parade it as a prestigious trophy, proving that he was no longer alive. Terrible things were done to the conquered king's remains by the victorious king. Brehon Laws were the order of the day and armies consisted of both men and women who fought side by side. At the same time in Ireland, small churches were being built, some being the provenance of just a single monk (usually nowadays referred to as "saints"). The townlands where small religious communities existed are often now known by the name of the 'saint' who founded them – e.g.: Cill Ghallagáin (Church of St. Galligan) or Cill Chomáin. Some of these small churches grew into religious communities of monks which got larger and more prosperous; others remained small and fairly insignificant. This period was the Golden Age of making illuminated manuscripts and craftworking of relics with gold and silver filigree in the monasteries. Some items, like the Cross of Cong or the Ardagh Chalice
