<p>Yes it's unheard of, mainly because every Hero summoned is not the real Hero but a clone as such they should not have memories of a previous war as the clone who has these memories is lost at the end. the bellow image and link explains it quite well</p>

<p>Saber did not reveal her identity to Shirou for fear of her master giving it away to enemies and thus exposing her strengths and weaknesses. But why, even though in front of a rival master, did she reveal the fact that she has been summoned to the previous Holy Grail War?

I don't think that Saber being summoned to "this era" necessarily implies to Rin that she was summoned in the Fourth War. There are presumably other magical systems that summon Heroic Spirits; Saber could've been pulled in by one of those. If I'm remembering right, Rin doesn't know that Servants don't retain memories of previous summonings. And Rin knows basically nothing about the Fourth War (not that Kiritsugu was a Master; not that Kiritsugu's Servant was a Saber; etc.).

Because there's nothing to gleam from the fact that she was summoned previously, infact in the Visual Novel she doesn't say that she was summoned in the previous War but was *"summoned once before"*, she doesn't mention that she was in the previous Holy Grail War until later on the 4th day where she and Shirou talk to one another before going to be where Shirou finds out she made it to the war's finale and questions his worth as a Master to her (since within the first night Saber had been in 3 fights and was badly injured in 2)

Also, Rin mentions when Saber says she was summoned previously that it was quite rare. given what we know about the previous Wars with the exception of 3 no hero has been *properly* summoned twice under the Fuyuki System, the exceptions are
