 Not much remains of Stela 18 , and what is left is badly worn . However , archaeologist <unk> Morley claimed that it expressed a Calendar Round date of 6 <unk> 13 K <unk> ( corresponding to a Long Count date of 9 @.@ 17 @.@ 5 @.@ 0 @.@ 0 or <unk> 27 , 775 ) , which Martin and Grube note is within Ha ' K 'in Xook 's reign . Stela 23 is the king 's accession monument . Originally carved on all four faces , this stela is in poor condition because it tipped over and shattered . The largest portions remaining include the base , and remnants of a basal panel of <unk> that feature the feet of two individuals . Similar to Stela 18 , Martin and Grube argue that Stela 23 dates to the rulership of Ha ' K 'in Xook because the Calendar Round date on the monument is contemporary with the date found on Stela 13 . This stele details a <unk> <unk> <unk> ceremony for Ha ' K 'in Xook 's dead father , Itzam K 'an Ahk II , and , when translated , reads " Ruler 6 [ Ha ' K 'in Xook ] , child of Ruler 4 [ Itzam K 'an Ahk II ] … acceded to the rulership " , seemingly proving that Ha ' K 'in Xook was indeed the offspring of Itzam K 'an Ahk II .
