In Vergilium Commentarius
Maurus (Marius) Servius Honoratus
VICTOR ALCIDES SUBIIT. Hic ius pontificale quibusdam videtur subtiliter tangere: domus enim, in qua pontifex habitat, regia dicitur, quod in ea rex sacrificulus habitare consuesset, sicut flaminia domus, in qua flamen habitat, dicebatur: quod hic ostendit ex persona Euandri, quem facit orantem ut Aeneas suam ingrederetur domum, non utique profanam, sed sacratam, scilicet quae fuerit hospitium Herculis, illis versibus ' haec, inquit, limina victor Alcides subiit, haec illum regia coepit' ....Regiae autem verius meminit dicendo ' tecta subibant pauperis Euandri' (et) ' Romanoque foro' : quis enim ignorat regiam, ubi Numa habitaverit, in radicibus Palatii finibusque Romani fori esse?
Victorious Alcides Entered. Here he seems to some people to touch subtlely on pontifical law, for the house in which the pontifex lives is called the Regia, because the king of the sacrifices (rex sacrificulus) customarily lived in it, just as the house in which the flamen lives was called the Flaminia. He shows this here by the person of Evander, whom he represents as praying that Aeneas might enter his house, clearly not profane but sacred, which of course was a lodging place for Hercules, with these verses: "These portals victorious Alcides entered, this royal house received him." ... Moreover, he mentions the Regia more accurately by saying "they approached the house of poor Evander" and "in the Roman Forum," for who does not know that the Regia, where Numa lived, is at the foot of the Palatine and in the confines of the Roman Forum?
