On May 8, 2020, Cortada made 454 marks on the coastline of Key Biscayne, one of Miami’s barrier islands, as part of a ritualistic performance to honor the 454 neighbors who had died due to complications from COVID-19 as of that date. Although waves washed Cortada’s markings away, those impacted by these deaths will never forget their loss – and, conceptually, the waves share our grief with those also grieving on shorelines around the world.
