This book is one of four covering each region of Ireland and is part of the authors attempt to create a resource to complement their comprehensive reference volume Irish Aquatic Monsters-A Survey and Definitive Guide. Combining folklore records, historical articles and their own research it is designed to give an overview of the historic, folkloric and mythological record of aquatic monsters associated with Connacht; Galway, Connemara, Leitrim, Sligo and Roscommon. From the water-horse or aughisky to the horse-eels of Connemara. Each volume has geo-spatial co-ordinates for monster locations, a suspect list and in-depth documented accounts from each lough with a monster association; from religious accounts to records from the National Folklore Collection of Ireland. The authors have a genuine interest in this research and would love to hear from anyone who has used or read the guide for feedback purposes. In addition we would love to obtain supplementary information for use in the future. Further information and articles including a Google map detailing all of the recorded locations is available on our Facebook page Irish Aquatic Monsters.
