The motto was almost certainly taken from the title page of "Gentleman's Magazine", a monthly magazine published in London which had used it from its first edition in 1731, and was well known in the colonies. The motto alluded to the magazine being a collection of articles obtained from other newspapers, and was used in most of its editions until 1833. The motto was taken in turn from "Gentleman's Journal", a similar magazine which ran briefly from 1692 to 1694. While variants turn up in other places (for example a poem often ascribed to Virgil called "Moretum" contains the phrase "E Pluribus Unus"), this is the oldest known use of the exact phrase. Another source was some of the Continental currency issued earlier in 1776; these were designed by Franklin and featured the motto "We Are One" surrounded by thirteen rings, each with the name of a colony. This design is echoed in the seal submitted by the first committee, and the motto was quite possibly a Latin version of this concept.
