A: Città del Vaticano, Vatican City
Dating from the fourth or fifth century, the Codex Bembinus (Vatican Library Vat. lat. 3226) is the oldest surviving manuscript containing all or portions of the six comedies, or Fabulae, of Terence. It is written in Rustic Capitals.
"The marginal gloss is in a Cursive Half-Uncial, the handwriting of the educated person of late Antiquity which, as in this example, would often be used for annotation of formal works. It consists of a rapid form of Half-Uncial, as the name suggests" (Brown, A Guide to Western Historical Scripts from Antiquity to 1600  no. 7, plate 7).
In the middle of the 15th century the manuscript belonged to Gianantonio de' Pandoni (Porcellio) when in 1457 it was acquired by humanist Bernardo Bembo. It later passed into the collection of humanist, collector and archaeologist Fulvio Orsini, and entered the Vatican Library in 1600.
