Loxian 是一种艺术语言和人工文本(constructed script)，其名称的来源显然来自希腊语的 Loxos，意思是「间接的」，是作家及作词家罗马·莱恩为爱尔兰新世纪音乐天后恩雅于2005年发行的专辑《永恒之约（Amarantine）》所发明的语言；在该专辑里，Loxian 共出现在三首歌曲中，分别是 Less Than A Pearl「微弱的存在」、The River Sings「大河之歌」及Water Shows The Hidden Heart「水影心事」。

Loxian is an artistic language and alphabet created by lyricist and poet Roma Ryan. Roma Ryan is one of the music partnership triumvirate that is Enya. The language was created for Enya’s 2005 album Amarantine, which won a Grammy Award. Three songs on this album feature Loxian ("Less Than a Pearl", "Water Shows the Hidden Heart", and "The River Sings"). As Ryan explains in her notes on the 2010 box set The Very Best of Enya – “It has been a truly unique journey... We have journeyed from Aldebaran, the track that tells of the future migration of the Celts through space, to the three Loxian songs of Amarantine, which were born of Aldebaran.”
