According to the website of the Mercers' Company who are responsible for Trinity Hospital, the two sundials for the new Garden Building were commissioned in honour of the fact that the Greenwich Meridian passes through the site. The western dial is closest to the Line. ‘Every Christmas Day the shadow of the sphere on [the] gnomon traces the upper silver curve which crosses the hour lines. The lower gold curve marks Trinity Sunday 2007, the year in which the sundial was made’. The second dial is a noon dial. A spot of light falls though the star of the gnomon. Its position marks not only the exact moment of local noon (the vertical black line), but also the moment of mean noon (the silvery figure of 8 marking). The Latin motto is split across both dials and comes from Ecclesiastes (chapter 3, verse 1). It translates as: ‘To everything there is a season, and a time to every purpose under the heaven’.
