Baroque geographies: marginal preoccupations" The baroque signifier proliferates beyond everything signified, placing language in excess of corporality. At the risk of appearing still more paradoxical, we might say that baroque reason brings into play the infinite materiality of images and bodies." Christine Buci-Glucksmann (1994, page 139, emphasis in original)The baroque is a term that has hovered on the margins of geographic inquiry, barely mentioned in the vast swathes of geographic literature. Our intent in this theme issue is not to respond to this by bringing the baroque into the centre of our field, such that it becomes yet another correction to our spatial imagination (though, like the 'postmodern', the baroque is said to reappear at the end of every major stylistic transition). Nor do we wish to pin down the meaning of the baroque by scoping its key characteristics and posing these against other ideas, such as the topological (Allen, 2011;Dixon and Jones, 2015), even though one of the thematics proffered by the baroque is a twisting and turning of centres and margins, interiors and exteriors, insides and outsides. We hold, instead, that there is productive value in placing sustained attention upon the baroque's occupation of, and preoccupation with, the marginalia: that is, those sites where embellishments, flourishes, doodles, and side-notes bear a sometimes critical, sometimes tenuous relationship with the main text, but nonetheless an illuminating one. Our intent, then, is not so much to ask what a baroque geography is, or should be, but what a baroque geography can do.In the following we first provide a brief exegesis of the baroque that, whilst noting its emergence within particular times and spaces, yet emphasizes the fraught and questioning relationship between event and time, context and content, and reality and representationall of which the baroque has come to indicate. It is with this fraught lineage in mind that the subsequent papers that make up this themed section, from diverse areas of geographic inquiry, can be read. Certainly, there is a great deal written in the arts and humanities on the emergence and development of the baroque as both a form wherein, for example, nature exceeds formal conventions-as with the malshaped pearls (les perles baroques) of 16th-century France, or the bizzarerie of 17th-century Italian architecture-and as an attitude denoting an unrestrained eccentricity and a perverse quest for novelty. Whilst in the 18th century such an attitude was understood as pertaining to the strange and the unusual, by the 19th century the baroque taste came to be allied with decadence and decline as religion collapsed into politics, and the superabundant detail of the Counter-Reformation, which both pleasured and stupefied the senses, became a tool of policy (Hills,
