Heinsius' note is something of an oddity. He begins by reading AVREA for the AENEA of most manuscripts, taking _uel eburna uel aurea custos_ to refer to the chryselephantine statue in the Parthenon, 'sed altius consideranti locum apparet de duplici statua Mineruae agi, altera eburnea, altera aenea'. _Aenea_ therefore continued to be the accepted reading until 1873, when Haupt (_Opuscula_ 584) pointed out that it was unmetrical, and restored _aerea_, found in some manuscripts.
The inverse error occurs at _Her_ VI 32, where most manuscripts have the unmetrical _aeripedes_ for _aenipedes_. But Merkel, followed by Palmer, considered 31-38 an interpolation; and _aeripedes_ may have been what the interpolator wrote.
=32. PHIDIACA ... MANV.= Ovid is recalling Prop III ix 15 'Phidiacus ... Iuppiter'. For the Latin poets' use of a personal adjective for the genitive of the noun, see Austin's interesting note on _Aen_ II 543 _Hectoreum_.
=33. VINDICAT VT CALAMIS LAVDEM QVOS FECIT EQVORVM.= 'As Calamis lays claim to the praise given his horses'. Calamis, a sculptor of the fifth century BC, was particularly famous for his statues of horses; see Pliny _NH_ XXXIV 71 'habet simulacrum et benignitas eius ['Praxiteles' generosity is seen in one of his statues']; Calamidis enim quadrigae aurigam suum imposuit, ne melior in equorum effigie defecisse in homine crederetur. ipse Calamis et alias quadrigas bigasque fecit equis sine aemulo expressis'.
=33. QVOS FECIT EQVORVM.= Similar instances of hyperbaton at 28 'quod fecit quisque tuetur opus', _Met_ IV 803 'pectore in aduerso quos fecit sustinet angues', and _Fast_ VI 20 'tum dea quos fecit sustulit ipsa metus'.
=34. VT SIMILIS VERAE VACCA MYRONIS OPVS.= The _Cow_ of Myron (late fifth century BC) was his most famous work. Praise of the statue's lifelike appearance was a stock theme of Hellenistic writers of epigram; it appears from Pliny _NH_ XXXIV 57 that the poetry written about the statue was as notable as the statue itself. Thirty-six poems of the Palatine Anthology deal with the theme (IX 713-42 & 793-98). Ausonius wrote eight epigrams on the same subject (_Ep_ LXVIII-LXXV), of which I quote LXVIII as a typical example of what both the Greek and Latin epigrams are like:
