IMBREX (καλυπτήρ). A ridge-tile made to receive the shower (imber), and of a semi-cylindrical form, as contradistinguished from tegula, which was flat. (Isidor. Orig. xix. 10. 15. Plaut. Most. i. 2. 26.) The imbrex was intended to cover the juncture of two flat tiles, and, consequently, was made narrower at one end, so as to lap over one another and form a continuous ridge down the sides of the roof (woodcut s. IMBRICATUS), which threw off the rain water from its hog's back into the channel formed by the tegulae, between each row of imbrices. The modern Italian architects use tiles of the same description; two of which are represented by the annexed engraving (Imbrex/1.1), which shows their form, and the manner in which they were fitted to one another.

2. Imbrex supinus. A gutter formed by a series of ridge-tiles fitted into one another, and laid upon their backs (Columell. ix. 13. 6. Compare ii. 2. 9.), as in the annexed example (Imbrex/2.1), which shows a water conduit in the ruin, commonly known as the grotto of Egeria near Rome.
