Our mind is an archive. In it, we process, sort out and store away all kinds of information. Into a black box of grey matter, to get back to it sometime. What happens when memories do not want to be archived, and their place in the mind remains blank? This book asks for the accessibility of trauma, moving between the individual and societal scale. Between blurred borders of public and private, it looks at how traces of trauma appear and disappear. How do they manifest in our daily encounters? Coded, decoded, and eventually, waiting to become apparent. Gathering these coded languages in a codex, this piece of printed matter allows us to reflect on past knowledge while opening up political questions about privacy in the domestic realm. How does trauma reside in intergenerational cycles, and when does it become tangible?
