The Lady Mother is a Caroline era stage play, a tragicomedy generally attributed to Henry Glapthorne, and dating from the middle 1630s.
Never printed in its own era, the play survived in a manuscript marked as a theatre prompt-book, revealing significant details about the stage practice of its time.
[5] The MS. is a scribal copy, and shows repeated revision; it reveals Glapthorne working with his scribe to shape the final text.
[6][7] The Revels office (specifically William Blagrave,[8] the assistant of the Master, Sir Henry Herbert) demanded some changes in the text,[9] and several lines are crossed out, to be omitted from performance.
F. G. Fleay speculated that The Lady Mother was an alternative title for The Noble Trial, a Glapthorne play that was among those in the collection of John Warburton that were destroyed by fire.
