Pliny was allowed home (Rome) at some time in AD 75–76. He was presumably at home for the first official release of "Natural History" in 77. Whether he was in Rome for the dedication of Vespasian's Temple of Peace in the Forum in 75, which was in essence a museum for display of art works plundered by Nero and formerly adorning the Domus Aurea, is uncertain, as is his possible command of the "vigiles" (night watchmen), a lesser post. No actual post is discernible for this period. On the bare circumstances, he was an official agent of the emperor in a quasiprivate capacity. Perhaps he was between posts. In any case, his appointment as commander of the imperial fleet at Misenum took him there, where he resided with his sister and nephew. Vespasian died of disease on June 23, 79. Pliny outlived him by two months.
