David J. McCutchion says that the roof of a ratna temple “is surmounted by one or more towers or pinnacles called ratna (jewel). The simplest form has a single central tower (eka-ratna), to which may be added four more at the corners (pancha-ratna)”. The number of towers or pinnacles can be increased up to a maximum of twentyfive. The ratna style came up in the 15th-16th century. McCutchion classifies the Parvatinatha temple as a standard saptadasa-ratna. Built in the 19th century, it has rich terracotta and stucco decoration and measures 21’ 6” square.McCutchion, David J., Late Mediaeval Temples of Bengal, first published 1972, reprinted 2017, pages 8-10, 55.
