the god protecting the threshold (limen) of the house. (Arnob. ad v. Gent. 1.15, 4.9, 11; Tertull. Idol. 15; August. de Civ. Dei, 4.8, 6.7.) Much superstition was connected among the Romans with the threshold, and many persons were very scrupulous in always putting the right foot across it first. (Petron. Sat. 30.)
