Jean-Baptiste-Gaspard d'Ansse (or Dannse) de Villoison (5 March 1750 (or 1753) – 25 April 1805) was a classical scholar born at Corbeil-sur-Seine, France.
[1] His chief discovery was a 10th-century manuscript of the Iliad—the famous codex Venetus A, with ancient scholia and marginal notes, indicating supposititious, corrupt or transposed verses.
[1] Hoping to find a treasure similar to the Venetian Homer in Greece, he returned to Paris to prepare for a journey to the east.
When the French Revolution broke out, being banished from Paris, he lived in retirement in Orléans, occupying himself chiefly with the transcription of the notes in the library of the brothers Valois (Valesius).
[3] Another work of some importance, Anecdota Graeca (1781), from the Paris and Venice libraries, contains the Ionia (violet garden) of the empress Eudocia, and several fragments of the Neoplatonists Iamblichus and Porphyry, Procopius of Gaza, Choricius, and the Greek grammarians.
