What do we know about the "Gospel of Barnabas"?

Ever so often, Muslims mention the 'Gospel of Barnabas'. What are the reasons that nearly everybody, who has studied it (including many Islamic scholars), believe that the is a (Muslim?) forgery from the Middle ages? The below references should give you enough material to ponder if you don't believe it.

The Muslim scholar Cyril Glassé states:

As regards the "Gospel of Barnabas" itself, there is no question that it is a medieval forgery. A complete Italian manuscript exists which appears to be a translation from a Spanish original (which exists in part), written to curry favor with Muslims of the time. It contains anachronisms which can date only from the Middle Ages and not before, and shows a garbled comprehension of Islamic doctrines, calling the Prophet "the Messiah", which Islam does not claim for him. Besides its farcical notion of sacred history, stylistically it is a mediocre parody of the Gospels, as the writings of Baha'Allah are of the Koran.

The Concise Encyclopedia of Islam, Harper & Row, 1989, p. 64

A concise discussion of the main issues is Samuel Green's article The Gospel of Barnabas

Often there is confusion between the "Gospel" of Barnabas and the "Epistle" of Barnabas in writings of Muslim authors.
The Epistle of Barnabas (the text).

    A Muslim started to write another list of contradictions between "Barnabas" and the Qur'an in a series of articles: [Part 1], [but], [he], [never], [even], [got], [to], [part], [2].

    Sox, David
    The Gospel of Barnabas
    London; Boston: George Allen & Unwin, 198, 152 pages
    ISBN 0-04-200044-0
    LC call number: BS2860.B4 S6

    The 'Gospel of Barnabas' was translated into English by Lonsdale and Ragg from Italian scripts a long time ago and it is widely available.

    Ragg, Lonsdale, 1866-1945
    Ragg, Laura Marie (Roberts)
    The Gospel of Barnabas
    LC call number: BS2860.B4 A3

    The Gospel of Barnabas document is not accepted as being authentic by reputable historians. The critical introduction of the Ragg book and the acutely perceptive book by Sox identify many of the inaccuracies. Sox, who has also written books about the Shroud of Turin, religious relics, and art forgeries, presents a particularly well done analysis. These two books are available through the inter-library loan service.

  dem Islam aus christlicher Sicht. - Teil I, Stuttgart (Germany) 1995.

A detailed insight into muslim propaganda using the "Gospel of Barnabas" 
is given to German readers in the book:

  Christine Schirrmacher: Mit den Waffen des Gegners. 
  Christlich-muslimische Kontroversen im 19. und 20. Jahrhundert. - 
  Berlin 1992  

Especially one may consult the chapter "Muslimische Stellungnahmen zur 
Verteidigung des Barnabas-Evangeliums" (pages 329-352). The book ends 
with an ample list of literature.

Schirrmacher points to a number of evidences for a fake in the late 
middle ages, as at least partly does Abdul Saleeb in his above linked to 
chapter: Erroneous geographic conceptions (Jesus sailes from Kapharnaum 
to Nazareth and from lake Genezareth to Jeruslam by ship), striking 
parallels to Dante's Divina Comedia etc.

    Part of the above is mentioned in her English web article The influence of German Biblical criticism on Muslim apologetics in the 19th century (about the middle of the article you will find the GoB discussion)

    The main issue in the Muslim-Christian controversy is the question whether the GoB is an authentic document from the first century by an actual disciple of Jesus. Since it is clearly not, we can learn little from the document about the actual person and teaching of Jesus and the GoB loses all propaganda value for Muslims. However, it is an interesting document about history of the Muslim-Christian interaction in the Middle Ages. Rod Blackhirst's studies The Medieval Gospel of Barnabas might be of interest to some in this regard. Moreover, he is now convinced to have solved the mystery of when, why and by whom the GoB was composed.
