Final answer:
The Psalter was not open and growing only in the beginning portion of the Old Testament period.
Step-by-step explanation:
The statement is false. The Psalter was not open and growing for only the beginning portion of the Old Testament period. Psalters were one of the most commonly copied works in the Middle Ages and played a central role in medieval church ceremony. They continued to be copied and used throughout the Old Testament period, not just in the beginning. The Psalter also underwent changes in terms of ink colors and versions of the text over time. For example, the Harley Psalter used the Roman version of the Psalms, while the Utrecht Psalter used the Gallican version.
