The twenty-four lines of this poem have been preserved only by the cod. Sangallensis 878 (variously assigned to saec. IX or IX-XI or XI-XII), whence it was edited in 1863 by K. SchenklSitzungsb. d. phil.-hist. Cl. d. kais. Akad. d. Wissensch. (Vienna) XLIII p. 71. A single line, the last, exists also in the cod. Bernensis 108 saec. IX. Fifteen survive in a MS of the 17th century now divided into two parts, Barberinus (or Barberinianus) XXXI 39 and Vaticanus 9135, the former containing the hexameters 3, 5, 15, 17, 19, 21, 23 and a spurious hexameter in lieu of 1, the latter the pentameters 2, 4,14,16,18, 20, 22, 24. The eight consecutive lines 6-13 are therefore missing from both ; and in this imperfect and interpolated form the poem was edited by Mommsen with Haupt's assistance inC.I.L. I p. 411.
