Note 13 — Chapter I · ROME UNDER THE KINGS.
Reading edition
“When Tarquinius Priscus regulated, with the foresight of a skilful prince, the state of the citizens, he attached great importance to the dress of children of condition; and he decreed that the sons of patricians should wear the bulla with the robe hemmed with purple: but even this privilege was restricted to the children of those fathers who had exercised a curule dignity; the sons of other patricians had merely the prætexta, and it was necessary that even their fathers should have served the prescribed time in the cavalry.” (Macrobius, Saturnalia, I. 6.)
