In an information age where everything is documented, categorised and defined does anything remain to be seen? A question most certainly for 2025. However, it has been asked before. At the turn of the 19th century, a time when organised religion was losing power and empirical science had confirmed almost all previous curiosities, people were asking the very same question. This talk introduces the spiritual artists of this era. We’ll discuss why they wanted to depict the soul and how we might approach their earnest work with our own present-day humanity.  From the spirit photographs, paintings and drawings by Hilma af Kilnt and Georgiana Houghton to the spiritual energies of colour, line and shape in the work of Piet Mondrian, Franz Marc and Wassily Kandinsky, we will explore how the development of abstract art in Europe was linked to a desire to depict unseen energies.
