Name and symbol
The origin of name of the city, Ljubljana, is unclear. In the Middle Ages, both the river and the town were also known by the German name Laibach. This name was in official use as an
endonym until 1918, and it remains frequent as a German exonym, both in common speech and official use. ) The city is alternatively named Lublana in many English language documents.
 The city is called
Lublana in Silesian,
Lubiana in Italian, in
Latin: Labacum and anciently Aemona.
For most scholars, the problem has been in how to connect the Slovene and the German names. The origin from the
Slavic ljub- "to love, like" was in 2007 supported as the most probable by the linguist
Tijmen Pronk, a specialist in comparative
Indo-European linguistics and
Slovene dialectology, from the
University of Leiden.
 He supported the thesis that the name of the river derived from the name of the settlement.
 The linguist
Silvo Torkar, who specializes in Slovene personal and place names,
 argued at the same place for the thesis that the name Ljubljana derives from Ljubija, the original name of the
Ljubljanica River flowing through it, itself derived from the Old Slavic male name Ljubovid, "the one of a lovely appearance". The name Laibach, he claimed, was actually a hybrid of German and Slovene and derived from the same personal name.
The symbol of the city is the
Ljubljana Dragon. It is depicted on the top of the tower of
Ljubljana Castle in the Ljubljana coat of arms and on the Ljubljanica-crossing
Dragon Bridge (Zmajski most).
 It symbolizes power, courage, and greatness.
There are several explanations on the origin of the Ljubljana Dragon. According to a
Slavic myth, the slaying of a dragon releases the waters and ensures the fertility of the earth, and it is thought that the myth is tied to the
Ljubljana Marshes, the expansive marshy area that periodically threatens Ljubljana with flooding.
 According to the celebrated
Greek legend, the
Argonauts on their return home after having taken the
Golden Fleece found a large lake surrounded by a marsh between the present-day towns of
Vrhnika and Ljubljana. It was there that
Jason struck down a monster. This monster has evolved into the
dragon that today is present in the city coat of arms and flag.
It is historically more believable that the dragon was adopted from
Saint George, the patron of the Ljubljana Castle chapel built in the 15th century. In the legend of
Saint George, the dragon represents the old ancestral
paganism overcome by
Christianity. According to another explanation, related to the second, the dragon was at first only a decoration above the city coat of arms. In the
Baroque, it became part of the coat of arms, and in the 19th and especially the 20th century, it outstripped the tower and other elements in importance.
