Rumi

or Ru'mia, are all connected with the old Latin word ruma, the breast, and are names for a divinity worshipped by the Romans as the protectress of infants (Varro. apud Nonium, p. 167; Donat. ad Terent. Phorm. 1.1. 14; Plut. Romul. 4). The sacrifices offered to her and Cunina consisted of libations of milk, and not of wine. Ruminus, "the nourishing," was also a surname of Jupiter. (August. de Civ. Dei, 7.11.) [L.S]
