parietina

1. Murus (μοῖρα, μείρω,) denotes any sort of wall, merely with reference to its form, without reference to its use, like τεῖχος; paries (πείρω) especially a wall, as the side of a building, or as a partition to separate the rooms, like τοῖχος; mœnia (ἀμύνω) the walls of a city, as a defence against the enemy, like περίβολος? maceria, the wall of an enclosure, to mark the boundaries and to exclude thieves, the garden or vineyard wall, like θριγκός. Virg. Æn. vi. 549. Mœnia lata videt triplici circumdata muro. And Flor. i. 4. Vitruv. viii. 4. Tac. Ann. xv. 43. Nero instituit, ut urbis domus non communione parietum, sed propriis quæque muris ambirentur. 2. Muri, mœnia, etc., are walls in a good condition; parietinæ, walls that are falling into ruins. 3. Mœnia denote walls as a defence of a city against a first assault; munimenta, the proper fortifications of fortresses and camps, which are of themselves a bulwark against being taken by storm. (v. 350.)
