With reference to the exhibition of these paintings at the Metropolitan Museum of Art, I quote from a full page illustrated article which appeared in the New York _Herald_ on Sunday, November 6, 1904, as follows: "The exhibition of these pictures of scenes connected with the history of the United States is not only an artistic but an educational event. Edward Moran was probably the strongest marine painter of the United States. * * * No more artistically valuable and educationally instructive exhibit has been made in New York than that of these paintings of Edward Moran. It is to be hoped that the school children of the city will be taken to see and study them. The public has already testified to its appreciation of the exhibition by its large attendance." It may be asked why the artist limited or extended the series to the number "13." This was done with a purpose. This number seems to have been interwoven in many particulars with the history of our country. The original colonies were thirteen, and also the first States; the first order for the creation of a navy was for thirteen war ships; there were and still are thirteen stripes, and there were originally thirteen stars, on our flag; on our coat of arms a mailed hand grasps thirteen arrows, as do also the left talons of the eagle, while in its right is an olive branch with thirteen leaves; there were also thirteen rattles on the snake on the first American flag, with the motto "Don't tread on me." It was on February 13, 1778, in the harbor of Quiberon, that the American flag received its first recognition by a foreign government, an incident represented by one of these paintings; thirteen years elapsed between the Declaration of Independence in 1776 and the inauguration of the first President, General Washington, in 1789; and the Louisiana purchase from France includes the area prospectively covered by thirteen States, as soon as Oklahoma and Indian Territories shall, as is now in contemplation, be admitted as one State. This idea of thirteen is already foreshadowed in the introductory painting "The Ocean," in which thirteen gulls are seen hovering over the water, typical of the important events, linked with that number, which would occur in the misty and unknown future. It is remarkable that although these paintings are by one man, and virtually on the same subject, they should exhibit such unusual variety, and be individually so exceptionally interesting. It has been said that historic pictures may be considered as either representative, suggestive or allegoric, but in this series of paintings all these elements are combined.
