I argue that the movements of post-memory appropriation are much more required in an age of social media, especially if we couple this phenomenon with the progressive disappearance of witnesses who knew the horror of the great tragedies of the 20th century. More than ever, we find ourselves facing the need to compare certain images from the past and to test their relevance and reliability. The further we depart from the witness’ lived experience, the more the question of recognition comes to the fore, particularly in the evermore frequent cases of memory-images that are no longer linked to memory bearers.
On this backdrop, my purpose will be to reflect on the strategies of remediation which consist in intersecting images from different media sources, relative to a same past event. I will suggest that these strategies are not guided by a logy of immediacy, but more by a logic of hypermediacy, which draws the attention on the materiality of the images themselves and elicits a more interactive participation of the spectator, favoring the emergence of an “hypermediated self” and the development of affiliative memories.
