1. The gardens, flowers, and groves in the two lines are elements of the conventional locus amoenus, as Libanius (Förster, 1.517.200).
2. Curiously, neither Proba nor Pomponius takes any units in this section from Silenus's cosmogonical account in Virgil's sixth Eclogue
3. For a discussion of how Christian poets (including Pomponius) respond to Virgil's Ecl. 1.6, see Fontaine , “La conversion,” 69–70 n. 21.
4. The question of whether the first Eclogue as it now stands was the first Eclogue that Virgil composed and published is a vexed one; a negative response is relatively safe. Even so, as Coleman Robert , ed. and comm., Vergil: Eclogues (Cambridge, 1977), 18–19 notes, there is no reason to doubt that the order of the poems in the first edition of the collected Eclogues, which likely dates to the early years of the Principate, was the one observed in the manuscript tradition. Ovid (A. 1.15.25) and Calpurnius Siculus (Ecl. 4.62–63) know the Tityrus poem as the first in the collection. In addition, two passages that I just cited, Virgil's own Georg. 4.566 and Vitalis's first-person Virgilian poem, suggest that the verse “Tityre, tu patulae recubans sub tegmine fagi,” was shorthand for the Eclogues precisely because it was the incipit of the collection.
