The colossal shape of a skull weighing four tons resonates with a sublime aura rather than fear because of its sheer scale. With its teeth clenched, it signifies the developed present and future outlook on the human civilization, which has been accomplished through patience, facing all oppressions as living beings rather than settling for eternity through death.¡®Vanitas¡¯ icons in Europe since the Middle Ages tried to convey the message of finiteness of life and eternity of death, but kwonjungho suggests that the development of human culture through history is an accumulated space of human thought and knowledge which has carried on for generations. The ¡®empty¡¯ skullsignifies healing of life by letting go of individual¡¯s greed and proclaiming the reverence for life and death. It lies as a ¡°mirror of time¡± before us, because it allows us to feel the eternity of absence in the fleeting life and to reflect on the time which the humankind has already passed, and still lies ahead in the future.
