Early Selfie (1865)

There was a discussion on Humanist about selfies and Emma Clarke on behalf of the Letters 1916 Project team posted a link to this holding of the National Library of Ireland, Augusta Caroline Dillon and Luke Gerald Dillon with camera on tripod reflected in a large mirror.

The two were apparently skilled amateur photographers who experimented with photographs like this. If one goes beyond photographs to paintings, I wonder if Las Meninas would qualify as a selfie.
