Before the Question

In 1650, an archbishop worked out that the world began on a Saturday evening in October, 4004 years before Christ. Not the year. The evening. And he was not being foolish. He was being rigorous.

Episode 1 of The Slow Machine goes back to before anyone thought to measure the Earth, when every culture already had an answer for what the ground is: Turtle Island, the body of a giant, a monster torn in pieces, a living mother who shakes when she is angry. Then the answers start to crack. A clergyman who refused to use miracles to explain the Flood. An irritable genius with a microscope who looked at fossil shells and saw creatures that no longer exist. A quarrel between water and fire. And a Scottish farmer in a small boat in 1788, looking at a cliff that made his friend "giddy".

The Slow Machine is a nine-part series on how we found out that the continents move, and why almost every clue came from an instrument built for something else entirely.

Next time: Episode 2, "The Shrivelling Apple" — the theory that explained mountains for seventy years, and a small reptile found on both sides of an ocean.
