ROSCIA, a plebeian family, having for its surname Fabatus, of Lanuvinian origin. It was at Lavinia, the ancient Lanuvium, and also at Rome, that I. S. M. R. -- Juno Sispita Magna Regina (Juno the Preserver, the Great Queen), was worshipped with particular devotion; and accordingly we find on the coins of this family (which are all silver, serrated, and common), L. ROSCI, with the head of the above-mentioned goddess covered with a goat skin, and behind it some small figure. On the other side FABATI, with the figure of one of her priestesses performing her allotted task of feeding the sacred serpent of the Lanuvian grove. Propertius gives an interesting description of this ceremony; -- Lucius Roscius Fabatus was a very great admirer of Julius Caesar, and was his quaestor in the year v.c. 698, in Gallia Transalpina. He is mentioned by Caesar himself in his Commentaries, amongst the Legati of the XIIIth Legion. -- Morell enumerates forty-three varieties
