Longus, Velius
a Latin grammarian.
Works
De Orthographia
He is known to us from a treatise De Orthographia, still extant.
Other Works
He was older than Charisius, who refers to his writings twice; first (1.18.2) to some work of which the title has not been preserved, and afterwards (2.9.4) to notes on the second book of the Aeneid. In a third reference (2.13.149) to certain observations on Lucretius, his name is an interpolation. The commentary on Virgil is mentioned by Macrobius (Macr. 3.6) as if it were one of the earlier compilations of this class (hunc multi alii commentatores secuti sunt), is noticed by Servius also (Ad Virg. Aen. 10.145), and in the collection of scholiasts upon Virgil published by Mai at Milan in 1818 from a Verona palimpsest. (Suringar, Hist. Scholiast. Lat. p. 184.)
Editions
The De Orthographia was brought to light by George Merula, and published by Fulvius Ursinus in his " Notae ad M. Varronem de Re Rustica," 8vo. Rom. 1587. It will be found in the " Grammaticae Latinae Auctores Antiqui " of Putschius, 4to. Hanov. 1605, p. 2214-2239.
