(anc. geog.), a lake of Japydia, the wealthiest district of Illyricum, to the south of the Save, and near the head of the Arfa. Now commonly called the Zirichitz Lake, from a small adjoining town. It is locked on every side with mountains; from which scanty currents run down; the lefs in quantity their waters, because drank up by the earth; till at length they are swallowed up in rocky furrows, so formed as to resemble artificial. In these the water being so redundant as to refuse receiving any more, they regurgitate, and return the water with extraordinary celerity; which thus spreading itself, forms a lake, in most places 18 cubits high. These waters afterwards retire with no less celerity than they came on, not only through the furrows, but pass through the whole of the bottom, as through a sieve; which when perceived by the inhabitants, they directly stop up the larger apertures, and thus take large quantities of fish: when the lake is dry, they cut down their harvest on the spot where they fowed, and sow again before the inundation comes on: and grass shoots so quick on it, that it may be cut down in three weeks time (Lazzus, Wernherus).
