A dead bird made of human bones. A coat of arms cast from melted beer cans. Memento Mori. In the eighteenth century, ossuary chapels filled with intricate constructions of human bones became important landmarks on Europe’s penitential and artistic map. Places such as the Sedlec Ossuary in Kutná Hora and the Chapel of Skulls in Kudowa-Zdrój, inscribed within the vanitas traditions of the era, served as reminders of the horrors of death, whilst clothing it in elaborate forms constructed from human remains. Okoński’s ossuary likewise commemorates death, yet perceives it as an absurd and grotesque moment — one so passionately celebrated in Polish martyrological ritual.
