 Several stelae have been found that were erected by Ha ' K 'in Xook , including Stelae 13 , 18 , and 23 . Stela 13 would appear to be the earliest , showing the oldest <unk> date assigned to Ha <unk> Xook , and it " captures the essence of the period @-@ ending celebration . " This 2 @.@ 39 @-@ metre ( 7 @.@ 8 ft ) tall stela retains stylistic elements of other niche stelae , but also shows a different form . It depicts the king scattering incense , similar to iconography found on Piedras Negras Stelae 2 and 32 . Clancy has argued that the stela contains iconography pertaining to three motifs : divination , " the quest " , and accession . <unk> is shown via the act of Ha ' K 'in Xook scattering the incense . This motif had been introduced earlier in the iconography of Piedras Negras by K 'inich Yo 'nal Ahk II . The stela also features Ha ' K 'in Xook wearing a unique headdress ; it is depicted as being composed of three knots and forehead scrolls , a projecting Water Lily Jaguar , and a flexible rectangular emblem made from a jaguar <unk> and a thick net . It has been postulated that this headdress was inspired by the headdress worn by an enthroned figure from the underworld featured on Stela 5 . Clancy argues that this headdress is a representation of " the royal theme of quest " , due to its <unk> similarity to other stelae at Piedras Negras . In addition , Stela 13 remains Ha ' K 'in Xook 's only extant image .
