Iris comes from Greek, named for the goddess who carried messages between gods and mortals along the rainbow, and the name is traditionally associated with communication and connection across distance. It's often read as suggesting someone who bridges different worlds rather than staying fixed in one place.
There are twelve signs, one of which is constantly ascending: the ascendant signifies the body, and the lord thereof the mind. Let not that sign ascend for your purpose, whose lord is impedited. - William Lilly (1602.-1681.)
