Known to most locals as the-lady-outside-the-Library, 'Tranquility' was one of Llew Summers' first major works. He remembered the public reaction at its unveiling: "There were heaps of comments about it, and about 20 or more people wrote letters to the Timaru Herald, but I seem to remember about nine of those letters were in favour, which was nice." He also said "[p]eople are quicker to criticise than compliment. I always prefer to have some response than none at all. All art should challenge to some degree. The work was a major turning point for me."
