Thebault's pencil of circles in an isotropic plane

In the Euclidean plane Griffiths's and Thebault's pencil of the circles are generally different. In this paper it is shown that in an isotropic plane the pencils of circles, corresponding to the Griffiths's and Thebault's pencil of circles in the Euclidean plane, coincide.
