In this episode of The Backstory on the Shroud of Turin, host Guy R. Powell speaks with Finnish researcher Teemu Hartikainen, founder and president of the Finnish Sindonology Society.
Hartikainen dives into one of the most debated documents in Shroud history: the 1389 memorandum by Bishop Pierre d’Arcis. Long cited as proof that the Shroud of Turin was a medieval forgery, Hartikainen explains why this claim doesn’t hold up.
Through detailed archival research, he reveals that the so-called “letter” is not a letter at all. Instead, it consists of two unfinished drafts dictated by the bishop. These drafts lack essential elements such as a date, signature, and polished Latin. Far from being official correspondence, they were likely internal notes, never intended for the Pope.
The episode also explores how later historians manipulated these drafts—adding a date stamp and altering translations—to make them appear as damning evidence against the Shroud. By mixing historical context with linguistic analysis, Hartikainen shows that these edits reshaped the meaning and fueled skepticism.
Beyond documents, the discussion uncovers the political and economic struggles of the time. With the Black Death devastating Europe and churches competing for pilgrims, the motivation behind d’Arcis’ complaints may have been financial survival rather than truth.
This thought-provoking conversation challenges long-standing assumptions and raises new questions about authenticity, faith, and history. Whether you approach the Shroud as evidence of the Resurrection of Jesus Christ or as a historical puzzle, Hartikainen’s insights provide clarity.
