Ancient Web: Sea Flags Catalogued the Navy’s Visual Language

Part of the Ancient Web Collection.

A flag aboard a ship is not merely decoration. It can identify a country, a commanding officer, a warning, or a message that would otherwise have to cross the water by voice or radio.

Joseph McMillan's website gathers illustrations, histories and explanations of flags and ceremonies used by the United States Navy and other American maritime services. Its main page carries a 2000–2001 copyright and says much of the material began as submissions to the Flags of the World mailing-list project.

From the ensign to the smallest pennant

The site map ranges across national colors, presidential and civilian officials' flags, Navy command pennants, battle streamers, yacht-club flags, shipping-company house flags, and international signaling.

These are not interchangeable pieces of cloth. McMillan explains their different uses and the rules governing when and where they appear. The site's Marine Corps section, for example, traces the battle standard through earlier designs and describes the size, colors and purpose of organizational flags and company guidons.

The signaling section expands the subject from ceremony to communications. It reminds readers that a collection of flags can function as a vocabulary between ships, even though the historical systems and their regulations have changed.

A bibliography with the depth of a filing cabinet

The references page is especially revealing. It lists official Navy and Coast Guard regulations, Marine Corps manuals, historic naval rules going back to 1799, and other printed studies. Readers can identify the documentary basis for an assertion rather than treating a drawing as self-evident authority.

The copyright notice also makes the maker visible. McMillan claims authorship of most text and illustrations and requests permission for reuse outside fair academic use. Preserving a useful site is not permission to copy its images into another publication.

A modern naval directive may supersede older instructions, so Sea Flags is best treated as a historical and specialist reference, not a replacement for current orders. Its particular achievement is collecting an extensive visual language under one stable set of links.
