It was often finished with a diced pattern. Between 1780 and 1830 it was highly prized for bookbinding, "Russia leather" was made in imitation of it. ]]></termNote><termCreatedDate>2026-03-30 21:02:54</termCreatedDate><relation><relationType>UF</relationType><termId>31456567</termId><termName>calf, Russia</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31456568</termId><termName>russia calf</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31438248</termId><termName>calf</termName><termType>PT</termType></relation><relation><relationType>RT</relationType><termId>31456514</termId><termName>Russia leather</termName><termType>PT</termType></relation></term>  </Zthes>
