SMELLING A PIG.
Two substantives respecting the same thing are put in the same case, as
Telemachum, juvenem bonæ indolis, Calypso existimavit.
Calypso thought Telemachus a nice young man.
By the way, what a nice young man Virgil makes out Marcellus to have been!
Praise, dispraise, or the quality of a thing is placed in the ablative, and also in the genitive case—as
Vir paucorum verborum et magni appetitûs:
A man of few words and large appetite.
Paterfamilias. Vir multis miseriis:
A father of a family. A man of many woes.
