EC'TYPUS (ἔκτυπος). Formed in a mould (τύπος, forma), which has the device intended to be displayed incavated in it, so that the cast (ectypum) which comes from it presents the objects in relief, like a terra-cotta cast (Plin. H. N. xxxv. 43.), as will be readily understood by the annexed engravings (Ectypus/1.1). The right-hand one represents an ancient mould, from an original found at Ardea, and the left-hand one shows the terra-cotta cast with its figures in relief which comes out of it.

2. Ectypa gemma, or scalptura; an engraved stone which has the images upon it carved in relief, like a cameo, instead of being cut into it, like a seal or intaglio. Seneca, Ben. iii. 26. Plin. H. N. xxxvii. 63.
