Dictionary of National Biography, 1885-1900/Blak, John
BLAK or BLACK, JOHN (d. 1563), a Dominican friar of Aberdeen, wrote ‘De reali præsentia Christi in Sacramento Altaris;’ ‘Acta colloquii cum Willoxio symmysta;’ ‘Conciones piæ;’ and ‘Monita ad Apostatas.’ His public disputation with John Willox took place in Edinburgh in the summer of 1501. Bishop Lesley gives the three heads of their disputation, and adds that in the end nothing was agreed. Indeed it would seem that the only important result of such discussions was to exasperate the temper of the people, for Blak was stoned to death by a protestant mob in Edinburgh on 7 Jan. 1562–3.
