A large stone plaque covered in glyphs was placed near the centre of the Ball Court #2, and a bit to the right of the ring overhead. This is the north section of the court. Here 74 glyph capsules are sculpted in a style indicative of the Late Classic, 600 - 900 CE. These record historical events involving the local dynasty that date back to the Early Classic, 300 - 600 CE.
About June 5, 465 CE, a local ruler with the title of Kalo 'mte', one of the most distinguished of the positions held at Coba, celebrated the end of a ten-year cycle. Then, 108 days later, October 21, 465 CE, another dignitary with the title Kalo 'mte' Ahaw dedicated a stone monument in the ball court. A third glyph records construction of a ball court in Kob'a', an earlier place-name for the site.
