=29. VIRIDI ... IVVENTA.= Ovid is perhaps imitating _Aen_ V 295 'Euryalus forma insignis _uiridique iuuenta_'. Similar phrasing at _AA_ III 557 'uiridemque iuuentam', _Tr_ IV x 17 'frater ad eloquium _uiridi_ tendebat ab aeuo', and _Tr_ III i 7-8 'id quoque quod _uiridi_ quondam male lusit in aeuo / heu nimium sero damnat et odit opus'; at the last passage Luck aptly cites _Met_ XV 201-3 'nam tener et lactens puerique simillimus aeuo / uere nouo [_sc_ annus] est; tunc _herba nitens_ et roboris expers turget'. =30. ALBENTES ... COMAS.= For the synecdoche compare Callimachus _Ep_ LXIV (=_Anth Pal_ V xxiii) 5-6 '[Greek: hê poliê de / autik' anamnêsei tauta se panta komê]'. Ovid would have been about sixty years of age at the time of this poem, old by Roman standards; but his father lived to ninety, and was survived by his wife (_Tr_ IV x 77-80). =30. INLABEFACTA= occurs in classical Latin only here and at viii 9-10 'ius aliquod faciunt adfinia uincula nobis / (quae semper maneant _inlabefacta_ precor)'. =31-32. QVAE NISI TE MOVEANT, DVRO TIBI PECTORA FERRO / ESSE VEL INVICTO CLAVSA ADAMANTE PVTEM.= Compare _Her_ II 137 'duritia _ferrum_ ut superes _adamantaque_ teque', _Her_ X 109-10, and _Met_ IX 614-15 (Byblis on her brother) 'nec rigidas silices solidumue in pectore _ferrum_ / aut _adamanta_ gerit'. Professor R. J. Tarrant notes the unexpected shift in the thought of the poem: earlier it was Ovid who was guilty of delaying in sending Tuticanus any sign of his friendship. Ovid might be postponing the real point of the letter for reasons of tact: Tuticanus has acted as though his long association with Ovid meant nothing to him, but Ovid does not want to complain of this openly, and so stresses his own failure to send Tuticanus a letter. =33-36.= The set of _adynata_ is remarkable for the way Ovid makes each of them relate to his own hardships; even Boreas and Notus have a specific connection, since Ovid complains so often of the climate of Tomis. =35. TEPIDVS BOREAS ... SIT.= A comparable inversion of nature described at _Ibis_ 34 'et tepidus gelido flabit ab axe Notus' (before Ovid will forgive his enemy). =35. PRAEFRIGIDVS= appears here for the first time in Latin; it occurs later in Celsus and the elder Pliny. _Praegelidus_, however, is found at Livy XXI 54 7. =36. ET POSSIT FATVM MOLLIVS ESSE MEVM.= The personal reference in the last element of the series of _adynata_ is a clear break with the conventions of the topic. The last (and therefore greatest) curse in the _Ibis_ has a similar personal reference: 'denique Sarmaticas inter Geticasque sagittas / his precor ut uiuas et moriare locis'.
