Rainbow Fraternity

Rainbow Fraternity, also known as Mystic Sons of Iris and W.W.W. Society, was a United States-based fraternity founded in the antebellum south that merged with Delta Tau Delta in 1886.

Founding and early years
Rainbow Fraternity was founded at the University of Mississippi in 1849 by seven students who had recently transferred from La Grange Synodical College, now a defunct college in Tennessee. The seven founders were John Bayliss Earle, John Bannister Herring, James Hamilton Mason, Robert Muldrow, Joshua Long Halbert, Marlborough Pegues, and Drew William Bynum.

Officially, the founders called their organization the Mystic Sons of Iris. In Greek mythology, Iris was the personification and deity of the rainbow, and the group's founders went to great lengths to incorporate symbolism connected to the rainbow of Iris into the fraternity's emblems and constitution. The original constitution, for example, was divided and subdivided into sections of seven (for the seven colors of the rainbow). There were seven officers for the chapter, each of which wore the fraternity's emblem enameled with one of the rainbow's colors. The ritual of initiation, too, contained seven portions, or degrees. Due to these associations, the Mystic Sons of Iris quickly came to be called simply Rainbow Fraternity or the W.W.W. Society.

Its second chapter came in the form of a colony at La Grange Synodical College.

The fraternity initially would only accept seven members at any one time, a tribute to the number of its founders, and no man from a northern state could be initiated. The low membership count that resulted led Rainbow Fraternity's to dormancy during the American Civil War. It was revived at the University of Mississippi, after the close of hostilities, spreading to several other schools in the south, and no longer confined by a membership cap.

Merger with Delta Tau Delta
On December 16, 1884, representatives from Rainbow Fraternity and Delta Tau Delta met in Nashville, Tennessee to finalize the terms of a merger of the two fraternities, the idea of consolidation having been informally discussed for the preceding two years. At the time, Delta Tau Delta president W.W. Cook explained the purpose of the merger was "to get a standing in good universities of the South, and the Rainbows had a corresponding design toward Northern colleges."

The Rainbow chapter at Southwestern University initially expressed optimism about the merger with Delta Tau Delta. As the terms of the compact became clearer, however, members began to have doubts. Rainbows at the University of Texas contacted their brothers at Southwestern and suggested both houses surrender their charters and defect to Phi Delta Theta, which had indicated it would be receptive to absorbing the displaced Rainbow members. In doing so, the Southwestern chapter became a new chapter of Phi Delta Theta, while the members of the Texas chapter were simply initiated into the existing Phi Delta Theta chapter on that campus.

Three other Rainbow chapters, at the University of Tennessee, Emory and Henry College, and Chamberlain-Hunt Academy were unwanted by Delta Tau Delta and Rainbow Fraternity withdrew the charters from those chapters so they would not be included in the consolidation. In the end, the Delta Tau Delta-Rainbow merger resulted in the larger fraternity only acquiring the Rainbow chapters at the University of Mississippi and Vanderbilt University, a process that became official in early 1886. At least one observer at the time questioned whether the Rainbow Fraternity had, in fact, merged with Delta Tau Delta or it was rather the case that two of its chapters had simply bolted Rainbow Fraternity for the Delts. The heart of the question is whether the charters of Tennessee, Emory and Henry, and Chamberlain-Hunt had been legitimately revoked. The secret nature of the Rainbow constitution makes a more thorough assessment impossible.

During its existence, Rainbow Fraternity had also chartered chapters at Wofford College, Furman University, Erskine College, Southern Presbyterian University, and Neophogen College. All of these were inactive by the time the merger with Delta Tau Delta occurred.

Revival
In 1889, Rainbow Fraternity was briefly revived at Wofford College by an alumnus who hadn't received the news that the fraternity had merged with Delta Tau Delta. It subsequently disbanded on learning the fate of its parent organization.

Symbols
Rainbow Fraternity's colors were the seven colors of the rainbow and its emblem was the rainbow. Its patron Greek divinity was Iris. For many years, its password was "W.W.W."

The fraternity's original badge was modeled after the Roman fasces, consisting of a half cylinder and a bundle of seven rods surrounded by a Roman hatchet. The rods were held by three bands that were colored with one of the seven rainbow colors, with each of the chapter's seven members having a badge featuring a different color.

The badge was changed in 1874 to a semicircle rainbow above three Ws. The middle W was twice the size of the outer two and was decorated with seven stones; the badge's owner could select the stones' color. Over the middle W, under the rainbow, was the chapter's initial letters. Although this badge was originally designed to have the rainbow in enameled rainbow colors, it was more often made with a black enamel rainbow shape that was surrounded by a narrow band of color.

The Rainbow Fraternity's seal was identical to its second badge, with the addition of two surrounding circles. The words “Enios Iridos” was located between the circles, at the top. The university's name was located between the circles at the bottom.

Legacy
Under the terms of its merger with Delta Tau Delta, several elements of the Rainbow Fraternity were preserved.
 * Rainbow's official publication, The Rainbow, became the official publication of Delta Tau Delta, replacing the latter fraternity's The Crescent.
 * A Rainbow ritual, the Rite of Iris, was preserved and incorporated into Delta Tau Delta work, becoming the combined fraternity's pre-initiation ceremony.
 * The new southern division of Delta Tau Delta was named the Rainbow Division.
