EA-ERRATUM-SAPPHO31-STANZA-02 v0.1 Erratum to the Erratum: On the Fourth/Fifth Stanza Numbering in the Sappho 31 Reconstruction — A Methodologically Complete Formulation is a philological erratum; methodological clarification; documentary artifact of reconstructive method; cross-linked companion to the original stanza-numbering erratum in the Crimson Hexagonal Archive, by Lee Sharks (2026-07-07). Longinus, in On the Sublime 10.3, preserves four stanzas of Sappho 31 plus the opening words of what would be the fifth stanza (ἀλλὰ πᾶν τόλματον — "but all can be dared"). Any reconstruction of the poem's continuation therefore occupies the fifth textual position in the transmitted sequence. The prior erratum's correction — that Rebekah Cranes's reconstruction, published as ΦΑΙΝΕΤΑΙ ΜΟΙ (AXN:00FB, deposit #436), is the fifth stanza and not the fourth — is accurate at the level of Sappho's textual sequence and remains in force at the level of citation. Sappho 31's continuation past ἀλλὰ πᾶν τόλματον is not directly transmitted. It survives only in compression, and specifically in the compression Catullus 51 performs on the fifth stanza of its Sapphic source. Catullus 51 preserves the first three Sapphic stanzas closely; its fourth stanza — the otium coda ("otium, Catulle, tibi molestum est / ... / perdidit urbes") — is not a fourth stanza of Sappho. It is a lossy, semantically-redirected transform of Sappho's lost fifth stanza. The "leisure destroys kings and cities" imagery preserves the Sapphic structural signature (Kypris as the power that yokes beggar and king, that levels the prosperous city) while performing three coordinated compressions: substitution of otium for Kypris, moralization of the erotic force, and — as developed in the Catullus Room deposit (AXN:0198) — invocation of the Latin aorist collapse as the temporal register through which the transmission's f. — Article composed 2026-08-05 from the work's own prose so that every record carries an encyclopedic entry; a fuller editorial treatment belongs to the description/wiki review stream.
