vestra: i.e. of Furius and the two unpresentable members of his family whom Catullus does not mean to have him forget, his father and step-mother; cf. Catul. 23.5ff.
[2] opposita: with a play upon the meaning of ‘to mortgage’; cf. Pl. Ps. 87 “vix hercle opino [me posse mutuam drachumam unam dare], etsi me opponam pignori” ; Ter. Phor. 661 “ager oppositust pignori decem ob minas.”
[3] Apeliotae: cf. Plin. NH 2.119 “ab oriente aequinoctiali subsolanus … illum Apelioten Graeci vocant.”
[4] milia: etc. the sum was no great one, when 10,000 sesterces was a reasonable rent for merely a house in Rome (cf. Cic. Cael.7.17); but as Furius was at the bottom of his pocket, it is probable that he had mortgaged his house for all that he could raise on it. Catullus is scornfully indicating, therefore, the meanness of the house itself.
[5] 0 ventum: etc. 0 awful, fatal draft.
