This is a long article in French, originally published in 1921 in the Revue d'Assyriologie 18:161-198, that surveys rituals and amulets used across the ancient Near East to protect pregnant women against the Lamashtu demoness. "Labartu" is the earlier reading of Lamashtu. Thureau-Dangin provides the signs, transcription, and translation of a tablet from Seleucid-period Warka, a ritual from the Lamashtu series that uses magical stones to safeguard pregnancy. He compares the new text with the existing Lamashtu corpus (18 Lamashtu amulets and other related material). He argues that the key protection afforded by the ritual was that it compelled the Lamashtu to journey to the netherworld (l'Enfer).
