Rowbothamism

“Rowbothamism” is a term coined by Peter Markley, to help expose the revisionist history of flerfs and distinguish them from ancient flat earthers who believed the sun went under the earth.

Flerfs identify their view with ancient cosmologies. However in reality, when their view began with Samuel Rowbotham in the 1800s, it was completely new and unique in history due to its denial of sunset.

Considering this, when religiflerfs use the term “Biblical cosmology”, it is misinformation.

In his 1865 book Zetetic Astronomy: Earth Not a Globe, Rowbotham wrote:

Although the Sun is at all times above and parallel to the Earth's surface, he appears to ascend the firmament from morning until noon, and to descend and sink below the horizon at evening. This arises from a simple and everywhere visible law of perspective.

Pronunciation

Accounts seem to vary (even among UK English speakers) on whether the “TH” in “Rowbotham” is the dental fricative (like in “thin”), or a “T” sound with a silent H.

In a livestream discussion about this, at 2:01:35 Peter Markley and Michael Toon agreed to split the difference by:

• Peter using the “TH” sound like in “thin” and
• Michael using the “T” sound like in “bottom.”
