A knife in a loaf of bread,  a glowing candle, a dirty window, a Childs toy on a shelf, a clock, an hourglass all are enchantingly decorative to the average onlooker. For painters of the Gothic, Early Renaissance and High Renaissance periods, everyday household items were part of a powerful visual language.  William H. Hunt stated "When language was not transcendental enough to complete the meaning of a revelation, symbols were relied upon for heavenly teaching, and familiar images, chosen from the known, were made to mirror the unknown spiritual truth."

In a culture of limited literacy symbolic imagery was vital in enlightening the masses.  Byzantine, Gothic and Early Renaissance paintings are rich in philosophical and Christian symbolism regarding common household objects.
