VALVAE (θύραι διάπριστοι). A door or window-shutter which folds up (Cic. Div. i. 34. Juv. iv. 63. Plin. Ep. ii. 17. 5.); that is, when made in several leaves and joints, so that when opened they fold back one behind the other, like a screen, or the shutters of a modern window, as shown by the annexed example (Valvae/1.1), from a painting of Pompeii, in which the door is formed of four pieces, two for each leaf. (Varro ap. Serv. ad Virg. Aen. i. 449. valvae, quae revolvuntur, et se velant. Isidor. Orig. xv. 7. 4.) In one of the houses at Pompeii a door of the same description, in four parts, was placed between the Atrium and Peristylium, as has been ascertained from the marks left by it on the threshold. Mus. Borb. vii. Tav. A.B. Scavi, p. 7.
