Florentius (Spanish: Florencio; c. 918 – after 978) was a monk, scribe and artist of the monastery of San Pedro de Berlangas (Valeránica) in the County of Castile.
He may have been offered to the recently founded monastery of Valeránica as a child oblate or perhaps to its nearby mother house, San Pedro de Cardeña.
[1] The first record of Florentius's activity is the foundation charter of the monastery of San Andrés de Boada, which he drew up on 1 March 937.
That same day, he drew up Count Fernán González's charter of donation to the monastery of San Pedro de Arlanza.
[1] Florentius is recognized today for his calligraphy, his decorated initials, well executed frontispieces and miniatures and his work with interlace, relatively recently brought to Spain from the north.
On the same day, he drew up the count's donation of the monastery of San Quirce de Yesares at Añana to Valeránica.
