This is a dim and unpretentious constellation that can be found midway between Delphinus and the nose of Pegasus. It consists of three stars in a stretched isosceles triangle in a very barren field, the constellation itself is a little difficult to find, containing nothing of any interest to most observers. Invented by Hevelius in the 17th century, his "Little Horse" as Equuleus is translated, holds nothing even for the professional astronomer. From a historical perspective the constellation is mentioned by Ptolemy in the Almagest, as a part of the adjoining group of Delphinus, so perhaps Hevelius was being helpful in distinguishing it. In mythology it is thought to represent the small horse Celeris, the brother of Pegasus the winged horse and appears close to that group in the sky.
