Tiberius' grammatical activity on Homer (see especially Suet. Tib. 56 and 70) is here examined in the context of contemporary Roman culture and especially that of the emperor's own circle, dedicated to the allegorical and philosophical interpretation of the Homeric texts. An example of such activities is given by Seneca in his Letter 88, where he offers insights on both the nature and purpose of the liberal arts, with grammatical exegesis at front line, and the very education he had received in those arts as a young student during Tiberius'reign, thus casting light on the culture of that period.
