The year 2019 saw the centenary of Eddingtons eclipse expeditions and the corroboration of Einsteins general relativity by gravitational lensing. To mark the occasion, a Special Issue of Universe has been dedicated to the theoretical aspects of strong gravitational lensing. The articles assembled in this volume contain original research and reviews and apply a variety of mathematical techniques that have been developed to study this effect, both in 3-space and in spacetime. These include: ·Mathematical properties of the standard thin lens approximation, in particular caustics; ·Optical geometry, the Gauss-Bonnet method and related approaches; ·Lensing in the spacetime of general relativity and modified theories; black hole shadows.
