Barycentric coordinates are used to define mappings M from the plane of a reference triangle ABC to a circumconic. Accordingly, the M-image of a triangle is a triangle inscribed in the conic. Certain triangles T defined in this manner have relatively simple barycentrics and appear to be new to the literature. Cases are examined in which T is perspective to ABC, or to a family of cevian, or anticevian, or cocevian triangles. Of particular interest are criteria for perspectivity that involve cubic curves.
