The construction of miniature objects inside bottles appears to have begun in the eighteenth century, with the most favoured object being a ship. Possibly because it was a great way for sailors to pass the time on those long sea voyages. The oldest surviving example (dated 1784) is on display at the Museum of Art & Cultural History in Lubeck, Germany, and a real big one commissioned to grace the top of the fourth plinth on Nelson’s column in Trafalgar Square can now be found at Greenwich.
