Short answers, pulled from the story.
James Mabbe (1572-1642) was an English scholar, translator, and poet, and a Fellow of Magdalen College, Oxford. He translated major Spanish literary works into English, including Mateo Alemán's picaresque novel Guzmán de Alfarache in 1622, selections from Cervantes's Novelas ejemplares, and Fernando de Rojas's Celestina, published in 1631 under the title The Spanish Bawd.
The Spanish Bawd is James Mabbe's 1631 English translation of Celestina, or the Tragicomedy of Calisto and Melibea, a 300-page work by Fernando de Rojas described as a novel in dialogue. Mabbe's title highlighted the play's central figure, the go-between Celestina.
Mabbe may be the author of the fourth commendatory verse in the First Folio of Shakespeare's plays, published in 1623, which was signed only "I. M." The identification is supported by the fact that his friend and colleague Leonard Digges wrote the third verse in the same volume, but it has not been definitively confirmed.
