Octavo contemporary laced-through vellum with inked title to spine and yapp fore-edges (a few ink marks but vellum sound & clean). Colated complete [32]pp (title & prelims) + 768pp + [48]pp (index & errata). Circular stamp of St Ignatius College Amsterdam with release overprint on titlepage and neat early signature "Munckeri 1678". A few other annotations or underlinings, about 20 leaves near middle (pp405-439) have tan staining to top third of page not affecting legibility, so maybe present before book assembled for binding. Main notes are by Dutch humanist scholar Pontanus - his first published work. Text in Latin with some Greek. *Macrobius' Commentaries on Cicero's Dream of Scipio featured astral projection and foretelling the future, and his Saturnalia celebrate Roman festivals to honour the god Saturn. A nice tight copy with no worming, no loose pages or tears.
