In the first letter of his famous collection of correspondence, the Epistulae, Pliny the Younger credits Septicius’ constant urgings for motivating him to publish his letters. The intimate friendship between the two is evident in another letter where Pliny playfully chides Septicius for not appearing at a lavish dinner party.Pliny, Epistulae i. 15. In another letter, to Apollinaris, Pliny writes of Septicius Clarus: "I never met anyone more sterling, simple, frank, and trustworthy."Pliny, Epistulae ii. 9
