Calvinus was one of the finest sculpters known to history. While he performed many an exceptional pieces of historical figures, he is best known for his “inspired” pieces - pieces he created out of his own memory. He said he would go into his studio alone, then just “bang out” a piece without break. This process explains his prodigeous output. There are several dozen exceptionally lifelike women (and a few men). Most are beautiful and scantily clothed, but his “Old Washer Woman” is a master piece. Many countries consider Statues by Calvinus to be national treasures.
