The Noorderkerk, also known Vrouwenkerk
The centre door is in Empire style, dating from the early 19th C. The stone carving above, with the date 1647 shows a skeleton with a scythe, hourglass and ears of wheat and the words 'En Messem Immortalitatis' meaning 'see here the harvest of immortality'. In other words the comfortably off, worthy burger does not die but lives on in a changed form. We see him here as complete skeleton, reclining on a mat and supported with a cushion. The corn harvested with the scythe symbolises the harvest of immortality. The hour- glass is upright i.e. the sand (life) is still running through.
