Cumulus is a conceptual bridge between the notions of temporal, mnemonic, and geological layering.

Cylindrical cement pieces reminiscent of geological cores extracted from the depths of the Earth's crust and  arranged for scientific study become the canvas for a composite video made using a similar (yet fundamentally) different layering technique. The living timeline of the video flickers on top of the still geological sedimentation. 

​

This piece addresses anew the interweaving of time and matter, and questions the possibility of their non-linear interpretation.

Carbon Dating and Mnemonic Logs was presented at  Fractured Continuum (9 March - 30 April 2025, Sound Art Museum, Beijing, China), curated by Cheng Xi and art director Yu Er. Culminating Christova's 2-month residency with Elsewhere Culture and Dulwich College Beijing, the exhibition featured a series of works developed during her time in Beijing, as well as pieces and performances by local guest artists Ning An, Li Yanzheng, Xu Han and Yang Yu.
