Andromeda is one of the 88 modern constellations. Located north of the celestial equator, it is named for Andromeda, daughter of Cassiopeia, who in Greek mythology was chained to a rock to be eaten by the sea monster Cetus. Most prominent during autumn evenings in the Northern Hemisphere, Andromeda is one of the largest constellations, over 1,400 times the size of the full moon.
Here, Andromeda is shown together with Triangula - a variant of Triangulum using stars too small to feature in this star chart to make a second triangle - and the obsolete constellation Gloria Frederici. This illustration by Sidney Hall was included in Urania's Mirror, a set of 32 astronomical star chart cards first published in 1824.Illustration: Sidney Hall; restoration: Adam Cuerden
