Manuscript illuminator in the context of "Rossano Gospels"

Gerard David (c. 1460 – 13 August 1523) was an Early Netherlandish painter and manuscript illuminator known for his brilliant use of color. Only a bare outline of his life survives, although some facts are known. He may have been the Meester gheraet van brugghe who became a master of the Antwerp guild in 1515. He was very successful in his lifetime and probably ran two workshops, in Antwerp and Bruges. Like many painters of his period, his reputation diminished in the 17th century until he was rediscovered in the 19th century.

The Chronograph of 354 is a compilation of chronological and calendrical texts produced in 354 AD for a wealthy Roman Christian named Valentinus by the calligrapher and illustrator Furius Dionysius Filocalus. The original illustrated manuscript is lost, but several copies have survived. It is the earliest known codex to have had full page illustrations. The work is also called the Chronography or Calendar of 354, and the name Calendar of Filocalus or Filocalian Calendar is sometimes used to describe the whole collection, and sometimes just the sixth part, which is the Calendar itself. Other versions of the names ("Philocalus", "Philocalian", "Codex-Calendar of 354", etc.) are occasionally used. The text and illustrations are available online. It has had a variety of other names over the years; the historian Theodor Mommsen titled it "Chronica urbis Romae".

Amongst other historically significant information, the work contains the earliest reference to the celebration of Christmas as an annual holiday or feast, on December 25, although unique historical dates had been mentioned much earlier by Hippolytus of Rome during 202–211.
