Valerius Antias, and C. Licinius Macer, the father of Calvus, we have only fragments remaining.
C. Licinius Macer (died 66), who has been called the last of the annalists, wrote a voluminous work, which, although he paid great attention to the study of his authorities, was too rhetorical, and exaggerated the achievements of his own family.
The extant hexameter poem De viribus (or virtutibus) herbarum, ascribed to Macer, is a medieval production by Odo Magdunensis, a French physician.
Aemilius Macer must be distinguished from the Macer called Iliacus in the Ovidian catalogue of poets, the author of an epic poem on the events preceding the opening of the Iliad.
The fact of his being addressed by Ovid in one of the epistles Ex Ponto shows that he was alive long after Aemilius Macer.
