ĀNTLĬA

( ἄντλια ), any machine for raising water, a pump. The most important of these machines were:—(1) The tympanum; a tread-wheel, worked by men treading on it.—(2) A wheel having wooden boxes or buckets, so arranged as to form steps for those who trod the wheel.—(3) The chain pump.—(4) The cochlea , or Arch i me des’s screw.—(5) The ctesibica machina , or forcing-pump.—Criminals were condemned to the antlia or tread-mill. The antlia with which Martial (ix. 19) watered his garden, was probably the pole and bucket universally employed in Italy, Greece, and Egypt. The pole is curved, as shown in the annexed figure; because it is the stem of a fir or some other tapering tree. IMG:6459379820872971714_ill027a.jpg: Antlia.
