This article argues that gamma-acrostical disce in Horace’s Ode I 18 (ll. 11–15) alludes to the land-confiscatory acrostics recently identified in Virgil’s Eclogues (I 5–8; VI 14–24; IX 34–38). Horace has carefully signposted his acrostical intent. Virgil himself interfaces with this Horatian cryptography by means of other acrostics of his own. The result is an ‘acrostic conversation’.
