In Irish mythology, Connla's Well (also called the Well of Coelrind, Well of Nechtan, and Well of Segais) is one of a number of Otherworldly wells that are variously depicted as "The Well of Wisdom", "The Well of Knowledge" and the source of some of the rivers of Ireland.

Much like the Well of Nechtan (and some sources conflate the two), the well is the home to the salmon of wisdom, and surrounded with hazel trees, which also signify knowledge and wisdom.

According to the legend of Cormac mac Art, the well stands in the hall of the fairy king Manannán mac Lir.^{[citation needed]} In one legend, the well was home to the one Salmon of Wisdom until it was caught by the poet Finn Eces.^{[citation needed]} Nine sacred hazels of wisdom surround the well, blooming and fruiting in the same hour. Eating the hazelnuts that fell into the well, drinking the well water when the hazelnuts fell in, or eating the salmon that ate the hazelnuts granted knowledge and poetic inspiration. The well was accordingly sought out by many poets and philosophers.

Sir William Tyrone Guthrie (2 July 1900 – 15 May 1971) was an English theatrical director instrumental in the founding of the Stratford Festival of Canada, the Guthrie Theater in Minneapolis, Minnesota and the Tyrone Guthrie Centre, at his family's ancestral home, Annaghmakerrig, near Newbliss in County Monaghan, Ireland.

Guthrie was born in Tunbridge Wells, Kent, England, the son of Dr Thomas Guthrie (a grandson of the Scottish preacher Thomas Guthrie) and Norah Power. His mother Norah was the daughter of Sir William James Tyrone Power, Commissary-General-in-chief of the British Army from 1863 to 1869 and Martha, daughter of Dr. John Moorhead of Annaghmakerrig House and his Philadelphia-born wife, Susan (née Allibone) Humphreys. His great-grandfather was the Irish actor Tyrone Power. He was also a second cousin of the Hollywood actor Tyrone Power. His sister, Susan Margaret, married his close university friend, fellow Anglo-Irishman Hubert Butler. Butler translated the text for Guthrie's 1934 production of Anton Chekhov's Cherry Orchard, for perhaps its first English-language production.
