I read this beautiful article recently about how a tree's form tells the story of its individual past. Drought years baked in as narrow growth rings. Nuclear tests recorded as radiocarbon spikes. Or cramped growing conditions recorded in straight growth and a narrow canopy. History becomes embedded in tree flesh.
Human bodies pick up signs of life too, of course - the creases around the eyes that tell of tiredness and age, scars and stretch marks that bear witness to some of the changes and injuries we might undergo. I've been taken by the idea that tattoos give humans a way to take partial control of this narrative, to choose some of the stories that become imprinted on them.
The image I chose was inspired by Ernst Haeckel's line drawings of siphonophores, especially his Porpita prunella.
