It’s a subject that the geographer Maxim Samson discusses in his recently published book, Invisible Lines, which is an exploration of the hidden geographies that affect the way we exist in and move through our physical environments. These are lines that we experience and sense, consciously and subconsciously acting on them.I talk about these ideas in relation to the work of the New York-based artist Mika Rottenberg, whose film Cosmic Generator (2017) explores ideas about the movement and restriction of goods and people, and the visible and invisible divisions that are constructed to separate us.And I discuss the charcoal portraits of the British artist Frank Auerbach, whose practice of drawing the faces of his sitters and rubbing them out repeatedly in his quest to represent the truth suggests to me another kind of invisible boundary in space — that separation between two people that we can feel and sense but we can’t see.If you’d like to access the full podcast you can subscribe to it on my Substack publication at thegallerycompanion.com.
