Dear Andrew,

Following are a few examples from Euclidean Geometry:

1. Apollonian Circle:

This circle as locus-proposition appeared first in Aristotle, Meteor. III.
5.375b16 - 376b12

Reference:
Thomas Heath: Mathematics in Aristotle.
Bristol: Thoemmes Press, 1998, pp. 181ff.

2. On the Lemoine Point a.k.a. Grebe Point:

See the HM thred "Grebe":

3. On the Feuerbach Circle a.k.a. Euler Circle:
