Images of the hearts of various mammals have been created for around 30,000 years. The earliest known representation, recognisable by shape and anatomical location, is depicted in the mammoth or elephant painting in the Palaeolithic El Pindal Cave in Spain. Egyptian hieroglyphs from around 2,000BC include a heart depiction but it isn’t known if the glyph derives from a human heart or a bull. The oldest surviving depiction of a human heart with anatomical detail comes from the Olmec as an effigy vessel in the shape of a human heart (c900-1,200BC). The vessel has discernible features including a pulmonary artery, aorta, superior vena cava, interventricular succus and two ventricles. [Bendersky, 1997].
