My 5/29 posting “The hairy and the smooth” is about (among other things) a story from the biblical book of Genesis, about two fraternal twins, Esau the hairy brother and Jacob the smooth one — Esau also known as Edom, Jacob as Israel. Edom is the Semitic version of the name, Latinized as Idumea / Idumaea. Both Edom and Idumea gave their names to the lands of their descendants. From Wikipedia as quoted in my 5/29 posting:
Edom and Idumea are two related but distinct terms which are both related to a historically-contiguous population but two separate, if adjacent, territories which were occupied by the Edomites / Idumeans in different periods of their history.
My 5/29 discussion then turned to the shapenote song Edom. It turns out that the Sacred Harp has not only Edom (SH200), but also Idumea (SH47b), both song names from the placenames. Edom is joyous, but Idumea is something altogether different: by turns, powerful, moving, dark, mournful, literally apocalyptic, and shivery, a package that has has made it a great favorite of folk singers. Music from the Denson Sacred Harp (1991 revision):
(#1) SH47t Primrose and SH47b Idumea — both from the early flowering of shapenote music in the South in the early 9th century, both on salvation and resurrection, in Primrose (in A major) merely joyous; in Idumea (in A minor), triumphant, as part of the Apocalypse — texts from two amazingly prolific writers of hymn texts, Isaac Watts in Primrose, Charles Wesley in Idumea
