The art, craft, or technical field of creating anaglyptic works—relief carvings, engravings, and ornamental sculptures.
From anaglyptic plus -ics (forming a field of study or practice), similar to how 'linguistics' or 'aesthetics' name their respective fields.
If you study the techniques and history of Greek and Roman relief carving, you might say you're studying 'anaglyptics'—though art historians would more likely just say 'sculpture' or 'relief work.'
