There is no word Rubrum. If you mean Ruborem quem viderat, that would be "The redness ( or blush) that he-or-she had seen."
The correct quotation is 'rubum quem viderat', a reference to the burning bush which Moses saw. See the score of the motet of this name by Josquin on www.cpdl.org, where a translation of the full passage can also be found. - Mick Swithinbank
