Testing the Legend

The History of Lighthouses

Course 8 · Chapter 10 · Capstone: Testing the Legend

Lighthouses attract legends: the wonder of the ancient world, the wicked wreckers, the keeper driven mad, the three men who vanished. This last chapter pulls the course together: a timeline, a table that tests the claims from Chapter 1 against what the course found, a six-question method for testing any claim about lighthouses, and some advice on reading lighthouse history as a source. Dates are from the earlier chapters and flagged "check" where they were.

A Timeline of Lighthouses

Period	Strand (see chapter)
3rd century BC to the Middle Ages	The Pharos of Alexandria, Roman towers, monastic and coal lights (Chapter 2, check)
1690s to 1880s	The four Eddystone towers: Winstanley, Rudyerd, Smeaton, Douglass (Chapter 3)
1786 to 1850s	The Northern Lighthouse Board, the Bell Rock, Skerryvore and the Stevensons (Chapter 4)
1780s to 1900s	Argand lamps, Fresnel's lens, flash characteristics, fog signals, electric light (Chapter 5)
1801 to 1900	The Smalls, Grace Darling, the Flannan Isles: the keepers (Chapter 6)
1611 to 1957	Cordouan, the United States, Brunton in Japan, the empire and international standards (Chapter 7)
1732 to 1912	Lightships, lifeboats, the Plimsoll line and the Royal Charter storm (Chapter 8)
1980s onward	Automation, satellite navigation, heritage and the image of the lighthouse (Chapter 9)

Myths and Evidence

Claim from Chapter 1	What the course found
The Pharos of Alexandria was taller than any building of its day.	Unproven as stated: it was one of the tallest structures of the ancient world, but the pyramids rivalled it and its height is uncertain (Chapter 2).
Wreckers lured ships onto the rocks with false lights.	Not supported: plundering of wrecks is well documented, but luring with false lights lacks clear proof (Chapter 8).
Keepers were driven mad by loneliness.	Thinly supported: the logs and memoirs show routine and some hardship, with the boards choosing and rotating keepers (Chapter 6).
The Flannan Isles keepers were taken by something mysterious.	False as stated: three men were lost, most probably to the sea, and the mystery details were added later (Chapter 6).
Fresnel invented the lighthouse lens.	True only in a careful sense: he designed and introduced the compound system, building on earlier ideas (Chapter 5).
Lighthouses are obsolete.	False as stated: less essential for large ships, still used as a back-up, by small craft and as marks of danger (Chapter 9).

Testing a Claim: Six Questions

1. Who says it?

An engineer, a lighthouse board, a keeper, a novelist, a museum or a tourist office? Each has an interest.

2. What exactly is claimed?

Pin down the words: "first", "tallest", "mysterious", "saved". Define them before looking for evidence.

3. What would count as evidence?

Logs, board minutes, engineers' drawings, inquiry reports, newspapers of the time. Decide before you look.

4. Compared with what?

Other towers, other countries, other kinds of safety aid. A claim of importance needs a comparison.

5. Which period?

A light of 1650, 1850 and 1990 differ so much that a claim about "lighthouses" needs a date.

6. What would change my mind?

State in advance what finding would count against the claim.

Worked example: "Lighthouses made the sea safe" 1. It is said by the boards, by museums and by popular writers, who have reason to praise the lights. 2. "Made the sea safe" is vague: fewer wrecks, fewer deaths, or lower insurance costs? "Safe" is also relative. 3. Evidence: wreck and loss-of-life returns over time, insurance rates, and studies of causes of loss. 4. The comparison is with other changes, such as charts, chronometers, stronger ships, lifeboats and the Plimsoll line (Chapter 8). 5. The claim covers the 18th to the 20th century, over which the numbers changed greatly. 6. Evidence that losses fell as much where there were no new lights would count against it. Verdict: lighthouses contributed to safety, but did not do it alone, and "made the sea safe" gives them credit that belongs to many reforms (check).

Lighthouse History as a Source

It records structures and dates, the hard facts, though towers are rebuilt and altered and the date of a light may differ from that of its tower.
It records stories, such as Winstanley's wish or the Flannan Isles details. They add colour but are unreliable as facts (Chapters 3 and 6).
It records engineers' own accounts, which are first-hand and self-justifying (Chapter 4).
It records what is left out. The ordinary workers, the keepers' wives and the local people who used the lights appear in the sources only occasionally, and the sources must be read for their silences (Chapters 6 and 7).
Method. Use the boards' records and logs for facts, inquiries and newspapers for events, and literature and art for the image. Say which is which.

A British comparison The same method works on British maritime legends: the wreckers of Cornwall, the smugglers of the coast, the Spanish Armada wrecks on the Scottish and Irish shores, or the story of a famous ghost ship. Each can be broken down in the same way (who says it, what exactly, what evidence, compared with what, which period, what would change my mind). An Edinburgh reader might try the method on a local legend, such as claims about the Isle of May or the Bell Rock bell (check).

Check the details The timeline and tables summarise the earlier chapters, and their "check" items still apply. The verdicts are conclusions from the sources used in this course, not proof, and a different set of sources might shift the emphasis. Dates, dimensions and counts of lights change with each new history.

Exercises

Exercise 1

Choose one entry from the myths-and-evidence table (other than the worked example) and apply the six questions to it in a short paragraph for each.

→ Solution

Exercise 2

Take one famous lighthouse anecdote (Winstanley's wish, the Smalls, Grace Darling or another) and test it as a source: what supports it, who told it and when, and what would you want to see?

→ Solution

Exercise 3

Apply the six questions to a legend about a British or Scottish sea story and say what you conclude.

→ Solution
