Recently, a Dutch gentleman, whom we shall call Jan VIII, visited Leasowe and Bidston Lighthouses. I hope Jan VIII and his gracious wife will forgive me for greeting them with a paintbrush in hand.
Jan VIII was retracing the footsteps of his ancestor, Jan van Heukelom (1784-1847). The elder Jan, whom we shall call Jan IV, visited England in 1805 and kept a detailed journal of his travels. These were interesting times. England was at war with France, alarm beacons were erected on Bidston Hill in April, and the Battle of Trafalgar was fought on 21st October.
Here is an extract from Jan IV’s journal entry for Monday 16 September, 1805, when he paid a visit to Bidston Lighthouse. My thanks go to Jan VIII for sharing his annotated transcription, and to Woutera Willemsen for translating this passage from the Dutch.
“I then crossed the Mersey in a boat with Rogers and walked to the lighthouse with him. It is but a kind of tower, with a room containing the light for the ships to navigate by when sailing into the channel. The light is a cotton lamp wick supplied by oil placed in front of an enormous reflector. This reflector is, I noticed, in the shape of a parabola and the lamp is in its focus. The largest circle must be approximately 18 feet wide and the reflector is made up of trapezia of mirror glass. The front of the room in which the lamp is located is entirely made of glass, which means the light can be seen freely. Closer to sea there is another smaller and lower beacon. The helmsmen must keep these two lights in a straight line in a certain position in the channel. These circumstances, which the caretaker informed me of and his statement that the light was by far not as visible from the side as from the front, strengthened my thoughts concerning the parabolic nature of the reflector. This lighthouse can be seen clearly from Liverpool. The pilots used this circumstance by placing a number of signal poles close to the lighthouse. As soon as a ship arrives from sea and comes within sight of this beacon, it will hoist its private flag from which the caretaker will recognize the owner. The caretaker will then go and hoist the owner’s flag on the designated pole while a general sign will show what kind of ship it is. This is how the Liverpool merchants (want to) know what is happening at sea close by. When we arrived back from the lighthouse, we just had time to dine after our crossing, which seemed to last a long time to me. Afterwards, I dressed and went to the theatre with Mr Tait and company.”
Jan IV used the English terms for “lighthouse” and “signal poles”, and the French “reverbère” for “reflector”.Share this:
