It's not childbirth, but one god of this domain had a name mistranslated as "placenta king," and displaced an older god of it named Iah. During the Middle Kingdom, this domain was represented symbolically by a lake at Karnak, and by the youngest member of the Theban Triad, who was the son of Mut and Amun. One god of this domain allowed Kheru-Ur and four other new deities to be born from Nut after losing one seventy-second of his power, elongating the year by five days. This realm was represented by Khonsu, who lost a gambling game to Thoth. This object also corresponds to a body part removed in combat with Set. For 10 points, name this cosmic object which ancient Egyptians equated with the ripped-out left eye of Horus.
Social Science

A comic argument in this play turns on whether an available sofa was yellow or green. An attempted seduction goes awry when a woman reveals she is wearing clothes in mourning, but her seducer suggests she just take off her dress. A procurer leaves because she is scandalized by the presence of the mother of one of her former prostitutes. In addition to Madame Pace, other characters include one found dead in the fountain, the Girl, and the Boy, whose death from a mysterious gunshot causes the remaining figures to argue with the director over whether he's really dead or just pretending. FTP, name this play about the unnamed title figures who interrupt a rehearsal, a work by Luigi Pirandello.
Literature

The values of this property along certain lines are the semi-major axes of the Poinsot ellipse; the colatitude partial derivative of this quantity is zero along those lines, which are known as geometric principle axes. For planar translations, this property transforms by Steiner's theorem, which can be derived directly when one considers this quantity as a contravariant rank-two symmetric tensor. Its magnitude is equal to an object's area of gyration times its mass. For 10 points, identify the material property that is equal to the integral over a body of distance from an axis with respect to mass, is symbolized I, and is the rotational analogue of mass.
