Gaius Plinius Secundus, HN  7.3.34-35  (ca. A.D. 65):

Pompeius Magnus in ornamentis theatri mirabiles fama posuit effigies ob id diligentius magnorum artificum ingeniis elaborates, inter quas legitur Eutychis a viginti liberis rogo inlata Trallibus enixa XXX partus, Alcippe elephantum, quamquam id inter ostenta est, namque et serpentem peperit inter initia Marsici belli ancilla et multiformes pluribus modis inter monstra partus eduntur.

Pompeius Magnus among the decorations of his theater placed images of celebrated marvels, made with special elaboration for the purpose by the talent of eminent artists; among them we read of Eutychis who at Tralles was carried to her funeral pyre by 20 children and who had given birth more than 30 times, and Alcippe who gave birth to an elephant, although it is true that the latter case ranks among the portents, for one of the first occurrences of the Marsian War was that a maidservant gave birth to a snake, and also monstrous births of various kinds are recorded among the ominous things that happened.
