The Echo and the Stamp (EA-LONGINUS-01 v1.0) is a philological argument and constrained reconstruction by Lee Sharks, dated 2026-08-14, deposited as a working draft. Its subject is Longinus's De sublimitate, and its claim is that the treatise is a theory of transmissional inscription rather than a taxonomy of stylistic sources.
The argument proceeds from four passages. At 9.2 sublimity is defined as ἀπήχημα, an echo — a sound's return after the sounding has stopped — and its supreme instance is a silence: Ajax in the Nekyia, φωνῆς δίχα, greatness transmitting with the voice subtracted. At 1.3 the greatest writers are those who clothed the age with their own glory. At 7.3 the test of genuine sublimity is durability under repeated reception, stated as μνήμη δυσεξάλειπτος, memory hard to erase. And at 13.2–13.4 the mechanism of literary succession is named twice: greatness passes from the ancients as ἀπόρροιαι, effluences carried from sacred vents, and the transfer is ἀποτύπωσις, the taking of an impression — the same root as ἐνετύπωσε τῇ λέξει at 10.6, where Homer stamps a condition into diction.
The paper argues that these are not metaphors of Longinus's invention but the technical vocabulary of the two canonical ancient accounts of mind: ἀπόρροια from the physics of perception, ἀποτύπωσις from the wax-block model of memory whose verb for forgetting is ἐξαλείφεσθαι. Reading the ancients is described as perception; becoming great is described as retention.
The second half is a constrained reconstruction of the treatise's lost ending. De sublimitate breaks at 44.12 on ὡς ἡμῖν δοκεῖ, mid-return to πάθος — the one source of five announced at 8.1 and never treated. Because the period is syntactically complete and lands on the treatise's rank-1 clausula, grammar cannot constrain a reconstruction; promise, formula, address and prose rhythm do. Six Greek periods are proposed, every word attested either in the treatise or in Philo, De Specialibus Legibus I.65. A blind test derives, from Philo and the eight Slavonic Jesus passages of EA-LOGOS-01 with Longinus excluded, five terms an intermediary phase would require; four are supplied by the surviving treatise and the fifth is the reconstruction's own load-bearing claim — that a passion dissolves in the one who suffers it and remains in the diction.
The six periods are not offered as recovered wording, and the priority question is held open: Porter's The Sublime in Antiquity has not been read directly. Folds and supersedes EA-LONGINUS-TRANSMISSION-01 and EA-LONGINUS-JUNCTION-01.
