The Patrologia Latina Database contains
221 volumes and represents a complete electronic version of the
first edition of Jacques-Paul Migne's Patrologia Latina
(1844-1855 and 1862-1865).
Migne's Patrologia Latina was originally printed in 217
volumes from 1844 to 1855. There were two series: the series
prima, volumes 1-73, (Tertullian to Gregory the Great),
1844 -1849; and the series secunda volumes 74-217,
(Gregory the Great to Pope Innocent 3rd), 1849-1855.
Therefore the main chronological sequence of authors in the Patrologia
Latina runs from about AD 200 to AD 1216. However Migne did
incorporate medieval texts written after 1216 where these were traditionally
attached to an earlier work, often as a commentary or an introduction
While wanting to respect Migne's evident wishes, we have felt it
necessary to distinguish roughly between the medieval
and modern authors contained in the database. This
division allows searches excluding, or solely in, modern texts.
We have categorised authors as medieval and modern
according to modern scholarly practice by taking the year 1500 as
our guide. Although this year cannot definitively mark the end of
the "medieval" and the beginning of the "modern" age, it does capture
the sense of the two terms for modern scholarship.
