Menelai. This list contains nothing new except Robur Caroli, since
Columba Noachi (Noah's dove) had been raised to the skies by Bartschius
in 1624. The constellation Robur Caroli and also the star Cor Caroli
([alpha] Canum Venaticorum) were named by Halley in honour of Charles
II. of England.

In 1690 two posthumous works of Johann Hevelius (1611-1687), the
_Firmamentum sobiescianum_ and _Prodromus astronomiae_, added several
new constellations to the list, viz. Canes venatici (the Greyhounds),
Lacerta (the Lizard), Leo minor (Little Lion), Lynx, Sextans Uraniae,
Scutum or Clypeus Sobieskii (the shield of Sobieski), Vulpecula et Anser
(Fox and Goose), Cerberus, Camelopardus (Giraffe), and Monoceros
(Unicorn); the last two were originally due to Jacobus Bartschius. In
1679 Augustine Royer introduced the most interesting of the
constellations of the southern hemisphere, the Crux australis or
Southern Cross. He also suggested Nubes major, Nubes minor, and Lilium,
and re-named Canes venatici the river Jordan, and Vulpecula et Anser
the river Tigris, but these innovations met with no approval. The
Magellanic clouds, a collection of nebulae, stars and star-clusters in
the neighbourhood of the south pole, were so named by Hevelius in honour
of the navigator Ferdinand Magellan.

Many other star-groupings have been proposed from time to time; in some
cases a separate name has been given to a part of an authoritatively
accepted constellation, e.g. Ensis Orionis, the sword of Orion, or an
ancient constellation may be subdivided, e.g. Argo (ship) into Argo,
Malus (mast), Vela (sails), Puppis (stern), Carina (keel); and whereas
some of the rearrangements, which have been mostly confined to the
southern hemisphere, have been accepted, many, reflecting nothing but
idiosyncrasies of the proposers, have deservedly dropped into oblivion.
Nicolas Louis de Lacaille, who made extended observations of the
southern stars in 1751 and in the following years, and whose results
were embodied in his posthumous _Coelum australe stelliferum_ (1763),
introduced the following new constellations:--Apparatus sculptoris
(Sculptor's workshop), Fornax chemica (Chemical furnace), Horologium
(Clock), Reticulus rhomboidalis (Rhomboidal net), Caela sculptoris
(Sculptor's chisels), Equuleus pictoris (Painter's easel), Pyxis nautica
(Mariner's compass), Antlia pneumatica (Air pump), Octans (Octant),
Circinus (Compasses), Norma _alias_ Quadra Euclidis (Squar
