Cicero, De Inventione, in Latin, single leaf from a Romanesque manuscript, on parchment [France, second half of twelfth century]. Single leaf with virtual complete single column of 37 lines with only the final line shaved. Part 1. 3b of the text. A good and legible early bookhand with a strong ‘st’ ligature, a hairline ‘ct’ ligature and a few biting curves, larger ornate capitals in the margin, trimmed with loss to last line, a large 40mm flap from the binding (blank) , overall in good and presentable condition and on fine heavy parchment. 158 x 105mm. This is Cicero’s earliest extant work and the least likely survival of all his extant compositions. It sets out the art of oratory in four books (of which only the initial two survive) and was clearly written in his youth. Complete manuscripts are known from the Carolingian period onwards but they are exceptionally rare to the market and the Schoenberg database records none as having ever appeared on the open market and only one in private hands.
