St. Columba (521-597) founded a group of several significant monasteries in Ireland and Scotland. The Cathach, a sixth-century copy of the psalms in Latin, is traditionally ascribed to him and is the oldest extant Irish manuscript of the Psalter. The book’s decoration contains many elements of early Christian art but does not contain the interlacing scrollwork that would later become one of the hallmarks of Irish illumination. Many of its elaborated initials are directly related to the La Tène style, while others incorporate crescent-shaped motifs with conjoined spirals reminiscent of the Celtic Neolithic era symbol of the triskelion. An additional ornamental initial depicts a fish bearing a cross, a widely used Coptic motif suggesting a Mediterranean influence.

Another embellishment used in the calligraphic decoration is diminuendo. This textual design comprises a large capital letter followed by smaller letters, decreasing in size until equivalent to the lower-case size of the body of the text. This technique would be used to an even greater degree a century later in the Book of Durrow.
