Adam Tetlow | Ancient Metrology | From the Ridiculous to the Sublime | John Michell Memorial Lecture

If you are interested in ancient metrology and the discoveries of John Neal and John Michell, check out this new course by Adam, starting on 7th September 2025 :   / adamtetlowteaching  

Why is metrology a key to our study of the ancient world? How old could this science be? How do we use ancient metrology and avoid errors of reasoning in our analysis? How does the great pyramid teach us about this ancient science and about the nature of number itself? These questions have haunted and enlightened metrologists from past to present including the pioneers of the subject, John Michell and John Neal. Join Adam Tetlow for a matho-mythical exploration of the implications of metrology and its revelations of number and harmony.

He studied with Keith Critchlow at the Princes School of Traditional Arts, and has spent the last seven years working closely with the worlds leading authority on ancient metrology, John Neal, who recently passed away.
