^Urbain Vermeulen, Union européenne des arabisants et islamisants. Congress, J. M. F. van Reeth - 1998 "At Beelen's retirement Arabic disappeared from the programme, but it came back in 1885, when Jacques Forget was appointed professor of Arabic. The activity of this scholar was unimaginably varied: after defending a dissertation on the Syrian Afraates, he taught Arabic, the history of Arabic philosophy, ethics, dogmatics, Syriac, Hebrew (1925) and during a number."
