Deeper in the Pyramid, Share of Throat is the second edition of Deeper in the Pyramid, published at the occasion of the Milk exhibition at the Wellcome Collection, 2023. Deeper in the Pyramid, Share of Throat is a graphic novel with writing by Melanie Jackson and Esther Leslie. The novel is taking us on a journey of lactic abstractions, through the webs of bio-invasion and collective fantasy that interconnect various life forms through milk, its technologies and representations. The ontologies of species and gender have always been shaped by our relations with this primal liquid, and ensuring a ready supply has driven research in genetics, fertility and robotics. It is now open for radical transformation as new bio-organisms emerge, and real science merges with the fantastic.
