When does a depiction of the moon become a lunar map? This publication addresses this question from theoretical and historical standpoints. It is argued that moon maps are of crucial importance to the history of cartography, for they challenge established notions of what a map is, how it functions, what its purposes are, and what kind of power it embodies and performs. The publication also shows how terrestrial cartography has shaped the history of lunar mapping since the seventeenth century, through visual and nomenclature conventions, the cultural currency of maps, mapmakers' social standing, and data-gathering and projection practices. It further demonstrates that lunar cartography has also been organized by an internal principle that is born of the fundamental problem of how to create static map spaces capable of representing a referent that is constantly changing to our eyes, as is the visible face of the moon. It is suggested that moon maps may be classed in three broad categories, according to the kinds of solutions for this representational problem that have been devised over the last 400 years.

Renaissance Galway is the next ancillary publication from the Irish Historic Towns Atlas. The subject of the book is the remarkable 'pictorial map' of Galway, which was produced in the mid-seventeenth century. It offers a bird's eye view of Galway city at this time and presents insights into the cultural, sociopolitical and religious outlook of the local ruling elite - the so-called 'tribes' of Galway. Originally intended as a wall hanging, it was produced to impress and remains a centrepiece of Galway's visual history. Only two copies of the original printed map are known to exist and it is the well-preserved version from Trinity College, Dublin that is reproduced in Renaissance Galway. Following the format of previous map-guides from the Irish Historic Towns Atlas, the book presents carefully selected extracts from the pictorial map, each accompanied by a commentary. These range from descriptions of particular buildings or areas, to aspects of everyday life that are revealed in the map. In an introductory essay, the author ponders the many mysteries that continue to surround the pictorial map of Galway - its origins, compilers and purpose. Together the map extracts and accompanying texts offer a new perspective - a window into the culture and mindset of Galway's mid-seventeenth century ruling Catholic elite. The modern viewer is invited to inhabit the world of 'Renaissance Galway'. The Irish Historic Towns Atlas is a research project of the Royal Irish Academy and is part of a wider European scheme. www.ihta.ie
