These table-top viewers consist of a wooden stand supporting a hinged mirror and lens, used to view a flat image placed on the table next to the stand. A perspective effect is created through a combination of image design and lens and mirror properties. Surviving examples are elegant and highly collectible pieces of mahogany furniture, designed for the drawing rooms of affluent homes. ]]></termNote><termCreatedDate>2026-03-30 20:46:57</termCreatedDate><relation><relationType>UF</relationType><termId>31397785</termId><termName>diagonal mirror</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31397786</termId><termName>optical diagonal machine</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31397787</termId><termName>optical pillar machine</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31397788</termId><termName>zograscope</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31357453</termId><termName>optical toys</termName><termType>PT</termType></relation><relation><relationType>RT</relationType><termId>31401900</termId><termName>perspective view prints</termName><termType>PT</termType></relation></term>  </Zthes>
