This leaf is from the brief transitional period when the new technology of printing with movable type was combined with the more labor intensive methods of hand painting. The earliest printers were trained in the manuscript tradition and incorporated the conventions of historiated initials and illustrations into their early work. At first they left those spaces blank for the illuminator to complete entirely by hand. Later they developed printing methods (using woodcuts or iron engravings) to decorate the leaves.
This vellum leaf is from a Book of Hours from the transitional period when the new technology of printing with movable type was combined with the more labor intensive methods of hand painting. Illuminated manuscript books of hours were costly to make, and early printers realized the commercial value in printing larger quantities of illustrated books of hours at a lower cost. These printers tried to make their books of hours appear as similar to the manuscript books as possible, even going so far as to mimic the red lines scribes used to keep their text uniform. This leaf has numerous initials that were hand painted in red, blue and gold, including one three-line initial. The text includes Psalm 148, and beginning with the large initial "L" on recto, the text translates as:
Praise ye the Lord from the heavens: praise ye him in the high places.
Praise ye him, all his angels: praise ye him, all his hosts.
Praise ye him, O sun and moon: praise him, all ye stars and light.
Praise him, ye heavens of heavens: and let all the waters that are above the heavens
Praise the name of the Lord. For he spoke, and they were made: he commanded, and they were created.
He hath established them for ever, and for ages of ages: he hath made a decree, and it shall not pass away.
