In 1947 a group of famous people from the art world headed by an Austrian conductor decided to hold an international festival of music, dance and theatre in Edinburgh. The idea was to reunite Europe after the Second World War.
It quickly attracted famous names such as Alec Guinness, Richard Burton, Dame Margot Fonteyn and Marlene Dietrich as well as the big symphony orchestras (交响乐团). It became a fixed event every August and now attracts 400,000 people yearly.
At the same time, the “Fringe” appeared as a challenge to the official festival. Eight theatre groups turned up uninvited in 1947, in the belief that everyone should have the right to perform, and they did so in a public house disused for years.
Soon, groups of students firstly from Edinburgh University, and later from the universities of Oxford and Cambridge, Durham and Birmingham were making the journey to the Scottish capital each summer to perform theatre by little-known writers of plays in small church halls to the people of Edinburgh.
【Today the “Fringe”, once less recognized, has far outgrown the festival with around 1,500 performances of theatre, music and dance on every one of the 21 days it lasts. 】And yet as early as 1959, with only 19 theatre groups performing, some said it was getting too big.
A paid administrator was first employed only in 1971, and today there are eight administrators working all year round and the number rises to 150 during August itself. In 2004 there were 200 places housing 1,695 shows by over 600 different groups from 50 different countries. More than 1.25 million tickets were sold.
once less recognized, 是插入语，可无视
with around 1,500 performances of theatre, music and dance on every one 表伴随
of the 21 days it lasts. 时间状语修饰
当今的Fringe（专有名词），曾经没有被人们重视，现在已经远远超过了official festival（前文有提到），在它每次持续的21天中，有1500个左右的戏剧，音乐和舞蹈的表演
once less recognized 请翻译一下好吗？我想知道意思
曾经（once）被重视(recognized)的很少(less)，也就是几乎没有被重视（不好意思上面写的有点不精确）原句只是省略了being，其实是once being less recognized
...英语这个东西，句子一复杂了，只能意译
Today the “Fringe”（主）, once less recognized（定）, has far outgrown（谓） the festival（宾） with around 1,500 performances of theatre, music and dance on every one of the 21 days it lasts.（with短语做定语）
with around 1,500 performances （of theatre, music and dance定语） （on every one of the 21 days宾补） it lasts（定语从句）.
结构：with performances on every one(day) of the 21 days
