intaglio n [in-tal-yoh]
an engraving or incised figure in stone or other hard material depressed below the surface so that an impression from the design yields an image in relief;
the art or process of executing intaglios;
printing (as in die stamping and gravure) done from a plate in which the image is sunk below the surface;

Etymology: Italian, from intagliare to engrave, cut, from Medieval Latin intaliare, from Latin in- + Late Latin taliare to cut
The intaglio Mark created in his first semester at art school was both poorly designed and executed, leaving him not with the ornate and beautiful image he'd hoped for but rather what could only be describes as a hot mess.
P.S. Those of you who are mystery fans as well as word lovers' may enjoy The Broken Teaglass by Emily Arsenault. It's set in a dictionary publishers' office, the mystery is pursued by lexicographers and clues are found in the old word citation files so it's full of little details about words.
