Note 277-2 — LETTER FROM COLUMBUS TO FERDINAND AND ISABELLA CONCERNING THE COLONIZATION AND COMMERCE OF ESPAÑOLA273-1
Reading edition
The formal signature of Columbus which he enjoined upon his heir in his deed of entail, February 28, 1498. See P. L. Ford, Writings of Christopher Columbus, p. 90. If this letter was written, as is supposed, in 1493, this is the earliest use of this monogram. Its meaning has never been determined. The various conjectures are presented by Thacher, Christopher Columbus, III. 454-458.
