Charles Lyell
Can today's processes read the past?
That time, that place
A lawyer who moved into geology. When he began, the dominant view was catastrophism: that vast events like a great flood had shaped the land.
There was reason for it. The slow changes visible now seemed hopelessly inadequate to account for a mountain range.
Why this question
Lyell's principle is simple: assume the same forces acted in the past, at the same intensity, as act now.
No special events need be summoned. Only enough time.
What was found
He gathered evidence. Among the famous cases are the columns of the Serapis temple near Naples.
The lower part is clean, a band across the middle is bored through by marine molluscs, and above that it is clean again. The columns were raised, then submerged, then lifted back. The ground is still rising and falling now.
He stacked cases like this into three volumes, to show that no catastrophe is required.
The landscape was made by catastrophes such as a great flood
Mollusc borings on temple columns that sank and rose again
Darwin carried the book aboard the Beagle. Lyell himself could not accept evolution for a long time
