Extract from a Letter of Professor S.F.B. Morse, LL.D., to Rev. E. Goodrich Smith. "In the year 1812, I . . . [attempted] a large picture . . . 'The Death of Hercules.' . . . From [Washington Allston's] example I determined to model the figure of Hercules [in clay]. . . . I at first only completed it in that view [necessary for the painting]. At this point, Mr. Allston . . . advised me to . . . make a complete statue, . . . [and] recommended to send it to the Adelphi Society of Arts to compete for the prize. . . . [I] received . . . the Gold Medal. . . . [A] mould was made from the original clay model, from which were cast some five or six. I brought the mould with me from England, . . . a man in cleaning house . . . threw [the parts] into the street . . . so that the original mould is destroyed. . . . [One] of the casts from the original mould, was in the Pennsylvania Academy of Fine Arts, but was destroyed in the fire . . . A mutilated fragment of another is, or was in the National Academy. . . . Yours is the only perfect (so far as it is perfect) cast I know of, . . . It may be of interest to add one other fact in relation to this cast [that] Professor Morse . . . . presented it to me as a token of friendship, . . . to be placed in the Trumbull Gallery of Yale College, our common alma mater. Washington, Feb. 4, 1860. E. Goodrich Smith. [P. 7; exhibited under heading: "Sculpture."]
