An accidental death mask

"The handwritten French label on the reverse of this tiny plaster cast explains its history. In 1878, a stone Roman burial sarcophagus was found in the gardens of a Paris convent. When a tiny Roman child died 1800 years before, cement sealing the sarcophagus leaked inside and formed a mould of the child’s face. This plaster cast was created using that mould sometime between its discovery and 1920. The translation states the child was buried with a perfectly preserved small glass bottle. However, there is no indication of the cause of death."
