Maeciliam: dependent upofi an infinitive euphemistically omitted with solebant; cf. such constructions as Pl. Cist. 37 “viris cum suis praedicant nos solere” ; Mart. 3.76.4 “cum possis Hecuben, non poles Andromachen” .
 manserunt: etc. i.e. there are still two, but it is two thousand. If the reading be correct, the numeral unum, which is not infrequently joined with distributive pronouns, is here used instead of the distributive utrumque because of the contrast with the numeral milia; ‘to each one has accrued a thousand.’ But the expression of such an idea by crescere with an accusative with in is unprecedented, the meaning apparently demanding increscere with the dative.
