Star Tales - Lacerta (ianridpath.com)This inconspicuous constellation, sandwiched between Cygnus and Andromeda like a lizard between rocks, was introduced by the Polish astronomer Johannes Hevelius in his star catalogue of 1687 and depicted in his star atlas published posthumously in 1690. Hevelius gave it the alternative title of Stellio, a type of lizard also known as a starred agama, but this secondary name soon fell into disuse.
