Elizabeth Joscelin’s published advice for her unborn baby (The Mothers Legacy to Her Vnborn Childe) marks another landmark of 17th century female advice literature. The significance of this work in the history of feminism does not stop at the fact that it was written by a woman in early modern times, when women were not usually allowed to voice their thoughts in print form. The beauty of Joscelin's work lies in the multi-layered, well orchestrated imagery and language, which pronounce existential anxiety and fear of pregnancy more clearly than any other comparable mother's advice book in her times. By comparing her advice book with other books of the same genre, especially with Dorothy Leigh’s Mothers Blessing, this paper attempts to illustrate the salient features of her work. To appreciate fully the significance of these features, the paper also describes the historical shift of a religious discourse on maternal death. While noting the metaphorical collapse of gender distinctions in post-Reformation discourse on maternal death, the paper concludes that Joscelin’s text, especially the closet scene, registers rich interplay of binary oppositions between death and life, between private and public, and between woman and man, of course, not to strengthen but to problematize them.
