Note 527 — Chapter III · THE CLASSES OF THE POPULATION AND THE THEORY OF THE CONSTITUTION IN THE DEVELOPED REPUBLIC
Reading edition
The s(ine) p(atre) filii of Gaius (i. 64) and Plutarch (Qu. Rom. 103) was a conjecture of the jurists based on the abbreviated form of sp(urii) filii (Momms. Staatsr. iii p. 72 n. 4). Spurii filii was the official designation, while liberi naturales denoted the natural relationship to the father (Meyer Der römische Concubinat).
