Neckline: Bianchi decided to focus on other sculpted features of the bust "for the chronological criteria."[9] He made note of the "concave, raised neckline"[10] on the statue and compared the features of the neckline with other Ptolemaic statues of women from the Musées royaux d'art et d'histoire in Brussels, Belgium (English: Royal Museums of Art and History) and the Yale University Art Gallery in New Haven, Connecticut. The statues Bianchi used to compare with the ROM's piece were both dated between 200-100 BC.[11]
