1. “ longior quam lātior aciēs erat ” (Liv. 27.48) , the line was longer than it was broad (or, rather long than broad).
2. vērior quam grātior (id. 22.38), more true than agreeable.

[*] Note.--So also with adverbs: as, “—libentius quam vērius ” (Mil. 78) , with more freedom than truth.

[*] a. Where magis is used, both adjectives are in the positive:—

1. “ disertus magis quam sapiēns ” (Att. 10.1.4) , eloquent rather than wise.
2. “ clārī magis quam honestī ” (Iug. 8) , more renowned than honorable.

[*] Note.--A comparative and a positive, or even two positives, are sometimes connected by quam . This use is rarer and less elegant than those before noticed:—

1. “ clārīs mâiōribus quam vetustīs ” (Tac. Ann. 4.61) , of a family more famous than old.
2. “ vehementius quam cautē ” (Tac. Agr. 4) , with more fury than good heed.
