The planetary angels are not free-standing personalities. They are positions in a timetable, and Anael's position is Friday.
The scheme runs on the Chaldean order of the planets by apparent speed: Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon. Assign those in rotation to the twenty-four hours of a day and the planet ruling the first hour of each successive day steps through the familiar week. That is why the days are named as they are across Europe: dies Veneris gives vendredi and viernes, and the Old English Frigedaeg substitutes Frigg for Venus while keeping the same slot.
Anael holds the Venus slot. The Heptameron attributed to Peter of Abano, the compact operating manual that stands behind a great deal of later grimoire practice, sets out for each day its angel, its sigil, its perfume, the direction to face and the hours in which the work may be done. Friday's entry is Anael's.
The consequence is worth stating plainly, because it changes how the attribution should be read. To work with Anael in this tradition is to work at a stated hour on a stated day using a stated suffumigation. The angel is the name of a slot in a machine for scheduling ritual, and the machine matters more than the biography, because there is almost no biography to have.
The sephirotic Haniel of Netzach is the same name doing a quite different job: a position on a diagram rather than a place in a calendar.
