We light candles for birthdays, on cake. For weddings, christenings and funerals. We light them to say a prayer. We light them to give that romantic glow, to set the mood. They are lit during a power cut. They are great for subtle lighting at your dinner party, especially when the house is dusty.
They would be placed in a lantern on the windowsill, so folks could find their way home in the dark. Some of them are scented and fill the room with fragrance.
