The god protecting the threshold (limen) of the house. (Arnob. adv. Gent. i. 15, iv. 9, 11; Tertull. Idol. 15; August. de Civ. Dei, iv. 8, vi. 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.)
