The carved edge of the Sunstone measures almost 8 inches in width and has long been interpreted as a celestial or ‘sky band’ associated with the night. The band can be divided into two sections: viewed horizontally (Pic 1), the upper part (visible also from the front) - consisting of an extended series of dots - is generally accepted to represent stars. Separated by two lines, the lower part is believed to represent Venus. The rather complex Venus symbol alternates with sacrificial knives. These blades - tecpatl - are linked both to the planet Venus and to the rays of the sun. The whole band, according to Eduardo Matos Moctezuma, shows ‘the evening sun penetrating the underworld, night, Mictlan, the womb from which it will be born, triumphant, every morning.’

The Venus symbol in the sky band was described in detail by the German scholar and archaeologist Hermann Beyer back in 1921: ‘The morning star, the brightest star, was not represented simply by a white disk or by a round eye like the other stars [Pic 2], but rather by hanging stemmed eyes and flint knives that express the rays it emitted.’ Beyer was comparing a classic representation of the night sky in the Codex Borbonicus (Pic 2) with the symbols on the side of the Sunstone.
