Shaped, decorated, or created by carving; having been carved, often suggesting artistic work or antiquity.
Past participle of carve, from Old English ceorfan, from Proto-Germanic. The -en ending is an archaic or poetic form of the past participle, common in older English and still used for stylistic effect.
When you read 'carven stone,' you're hearing the ghost of Middle English—poets still use this form because it sounds more ancient and artistic, like the wood-carvers of fairy tales rather than modern 3D printing.
