Beatus vir are the first words in the Latin Vulgate Bible of both Psalm 1 and Psalm 112. In each case, the words are used to refer to frequent and significant uses of these psalms in art, although the two psalms are prominent in different fields, art in the case of Psalm 1 and music in the case of Psalm 112. In psalter manuscripts, the initial letter B of Beatus is often rendered prominently as a Beatus initial.
