He was an ignorant man, and liked to pass for a scholar; he sacrificed to Bacchus and Comus, and would fain be thought sober; he was lustful, bad-tempered, envious, and miserly, but yet would be considered a virtuous man. He loved hard work, and this forced him to abstain, as a rule, from dinner, as he drank so inordinately at that meal that he could do nothing after it. When he dined out he had to drink nothing but water, so as not to compromise his reputation for temperance. He spoke four languages, and all badly, and could not even write his native tongue with correctness; and yet he claimed perfection for his grammar and orthography, as for all his other qualities. While I was staying with him I became acquainted with some of his weak points, and endeavoured to correct them, at which he took great offence. The fellow writhed under a sense of obligation to me. Once I prevented his sending a petition to the Court, which the king would have seen, and which would have made Mengs ridiculous. In signing his name he had written ‘el mas inclito’, wishing to say your most humble. I pointed out to him that ‘el mas inclito’ meant the most illustrious, and that the Spanish for the expression he wanted was ‘el mas humilde’. The proud fool was quite enraged, telling me that he knew Spanish better than I, but when the dictionary was searched he had to swallow the bitter pill of confessing himself in the wrong. Another time I suppressed a heavy and stupid criticism of his on someone who had maintained that there were no monuments still existing of the antediluvian period. Mengs thought he would confound the author by citing the remains of the Tower of Babel--a double piece of folly, for in the first place there are no such remains, and in the second, the Tower of Babel was a post-diluvian building. He was also largely given to the discussion of metaphysical questions, on which his knowledge was simply nil, and a favourite pursuit of his was defining beauty in the abstract, and when he was on this topic the nonsense he talked was something dreadful. Mengs was a very passionate man, and would sometimes beat his children most cruelly. More than once I have rescued his poor sons from his furious hands. He boasted that his father, a bad Bohemian artist, had brought him up with the stick. Thus, he said, he had become a great painter, and he wished his own children to enjoy the same advantages.
