Other scholars have expressed a differing opinion, noting that the codex is similar in style to murals found at Chichen Itza, Mayapan, and sites on the east coast such as Santa Rita, Tancah, and Tulum.[4] Two paper fragments incorporated into the front and last pages of the codex contain Spanish writing, which led Thompson to suggest that a Spanish priest acquired the document at Tayasal in Petén.[13]
