Tracking Down a 17th-Century Treasure: Edam Museum’s Appeal for the Johan de Witt Letter

The Edam Museum is seeking help to locate the winning bidder of a remarkable 17th-century document: the Johan de Witt letter. Recently outbid at auction, the museum hopes to bring this autograph letter—dated 1670 and tied directly to Edam’s maritime story—home on loan. If you are, or know, the buyer of this unique piece, your support could illuminate a pivotal chapter in our permanent exhibition, Zeevarend Edam (Seafaring Edam).

In this post, you’ll discover what the letter is, why it matters to Edam’s nautical past, how to recognize the item, and how you can help us reunite it with the town that inspired it.

What is the Johan de Witt letter?

At its core, the Johan de Witt letter is a signed, pen-and-ink document dated “Haege den 21en Decemb 1670,” addressed to “Mijn Heere.” It bears the signature of Johan de Witt (1625–1672) and is intimately connected to Edam’s civic and maritime life.

Key identifiers at a glance

• Autograph Letter Signed (ALS) by Johan de Witt
• Dated: “Haege den 21en Decemb 1670”
• Addressed to: “Mijn Heere”
• Physical description: 1 folded leaf; (2) pages + (2 blank) pages
• Special features:
  • Cyclostyled transcript pasted onto p. 3
  • Owner’s stamp of the Pont family (Edam) on p. 4
• Auction reference: lot number 2987 at veilinghuis bubbkuyper

Summary of contents

The letter communicates various resolutions to the mayors and aldermen of Edam, including:

• The equipping of 36 war ships
• The “saecke van Munster en Bronswyck”
• The recruitment of a regiment in Cologne
• Amendments/extension and dispatch of several newly printed ordinances, including:
  • “inbrengen van Brandewijnen”
  • “quotisatie van zeep”
  • “divulgeren van Secreten”
  • “gepermitteerde winckels van Fransche manufacturen inde Steden”

Additionally, the museum’s interest stems from the letter’s direct link to the Edam timber merchant Pont, in which De Witt orders timber for the outfitting of 36 warships. The combination of civic governance, naval logistics, and local industry makes this document a rare lens on Edam’s role in the Dutch Republic’s maritime world.

Why the Johan de Witt letter belongs in Zeevarend Edam

Our permanent exhibition Zeevarend Edam tells the story of a town shaped by water. Historically situated on the Zuiderzee, Edam developed a deep bond with seafaring and trade. Edammers were highly sought-after sailors who served:

• In the merchant navy
• On fishing ships
• On whalers
• On ships of the VOC and WIC
• With the Admiralty of Amsterdam

This letter sits at the crossroads of those currents. It shows how Edam’s municipal leaders were directly engaged in broader naval affairs. It links the city’s timber trade and ship provisioning to the governance of war fleets, and it ties everyday local commerce to state priorities. For a gallery that explores the ways Edam’s people navigated global trade, fishing, whaling, and naval service, the document would provide a vivid, primary-source anchor.

A local story with national resonance

• The addressee is an Edam timber merchant (Pont)—a reminder that outfitting fleets relied on skilled regional suppliers.
• The communication to Edam’s mayors and aldermen places the town squarely within the decision-making and logistics pipeline.
• The references to 36 war ships, Munster and Brunswick, and recruitment in Cologne point to the complex geopolitical and administrative landscape of the time—seen from a distinctly Edam vantage point.

Exhibit synergy: connecting galleries and themes

• In Zeevarend Edam, visitors encounter objects and stories about Edammers sailing across fleets and oceans; the letter would add the administrative and material dimension (wood, outfitting, and municipal coordination).
• In the exhibition Edam in 14 highlighted steps, a detailed exploration of the Blaeu city plan reveals shipyards, mills, stacks of logs, and the contours of a maritime economy—precisely the ecosystem in which a letter like this lived.
• In From Yredam to Edam, the long arc from riverine settlement to prosperous trading town provides the historical runway for understanding why a 1670 state letter would reach into Edam’s civic and commercial life.
