In Weibo Village, Pingding, in the summer of the yisi year, there was a woman named Ma who was a sorcerer, aged over fifty, and who was pregnant for more than six years, finally this year giving birth to a dragon. When the officials asked after the cause of this, the woman told them that, after remaining pregnant for three or four years without giving birth, her husband, Registrar Cao, feared that the baby had changed into a demon, so drove her away. When the birth approached, she saw people descend from a haze and array themselves before her, as if they were within a government office. One person spoke to her personally, saying, “What has been entrusted to you over several years will today depart; next year the mother will be happy indeed.” When he had finished speaking, a white-robed person took her by the arm and departed; on reaching the gate, she grew confused and lost consciousness, only reviving after a long time had passed. The people around her said that three thunderclaps had emerged from dark clouds, and a dragon had flown from the woman’s body, leaving its mother behind.

 This would be the forty-second year of the 60-year cycle, so in this case perhaps either 1185 or 1245 CE.
