Associate Professor of Linguistics
I’ve studied roughly fifty or so languages, most of them dead:
What do these languages have in common?


For as long as humans have written, they have also left behind texts that later generations could no longer read. From undeciphered scripts carved into stone to fragmentary inscriptions preserved without context, these materials pose one of the most enduring puzzles in the study of language. How do scholars determine whether a set of symbols represents language at all? When it does, how can meaning, sound, and structure be recovered without a key?
This course introduces students to the principles and practice of decipherment: the study of unknown or poorly understood writing systems. Students will learn how decipherment differs from cryptographic code-breaking, what kinds of evidence are typically missing, and which assumptions are risky or unwarranted.
Through case studies of successful decipherments and famous failures, as well as hands-on analytical exercises, students will explore how frequency, distribution, structure, and cross-linguistic comparison can be used to reason about texts whose language and meaning are unknown.
Throughout the semester, students will work with real and simulated materials, developing and testing hypotheses about scripts and languages, and culminating in a final analytical decipherment activity that demonstrates their ability to apply the methods they have learned critically and rigorously.
By the end of the course, you will be able to:

(You can see that while not required, it’s really in your interest to come to class every day!)
There are three exams.
At the end of the semester, you will complete a final in-class analytical decipherment activity.
