A note on an old map led a diver to a shipwreck that had sat off the Isles of Scilly for nearly 350 years.

The British ship Phoenix, commanded by William Wildy, sank off the coast of Cornwall in 1680 with valuable cargo on board. Some of those recovered items will now go on display at the Isles of Scilly Museum, near where the ship went down.

Scuba diver and author Todd Stevens found the clue in an old map held in the archives of the National Maritime Museum in Greenwich. He saw the words “Cap Wildy lost” written over an area west of the island of Samson and decided to search the site, Divernet reported.

That search took him to the Western Rocks, part of the Isles of Scilly known for a long history of wrecks. Diving in depths from 15 to 130 feet, Stevens found the remains of a ship. He identified it as the Phoenix because of its unusual ballast, made from broken pieces of cannon.

Stevens recovered coins, jewellery, sword fragments, navigational instruments and personal items that likely belonged to the captain and crew, BBC News reported. He has since donated the artefacts to the Isles of Scilly Museum.

“It’s hard to believe these items have been sitting on the seabed for nearly 350 years,” museum curator Xavier Duffy said, according to Divernet. “This donation ensures that the material can now be shared with the public and preserved for future generations as part of the islands’ heritage.”

Phoenix was a 46-gun ship built in 1670. It sailed under charter to the East India Company. The ship sank near the Isles of Scilly on January 11, 1680, after bad weather. Much of the cargo from its recent trip to China was salvaged at the time.

The Isles of Scilly have a long record of shipwrecks. Nearly 1,000 ships have been lost there over the centuries. BBC News said poor visibility, crowded fishing channels and hidden rocks have all played a part.

“The coasts of the Scilly Isles and West Cornwall have probably proved more lethal than any comparable area in the world,” John Fowles wrote in his 1974 book Shipwreck.
