owe their force, in part at least, to the personality of their author,
and to the happy moment of their production, has evanesced. Here,
however, is one which seems still to bear the impress of Alberti's
genius: 'Gold is the soul of labour, and labour the slave of
pleasure.' Of women he used to say that their inconstancy was an
antidote to their falseness; for if a woman could but persevere in
what she undertook, all the fair works of men would be ruined. One of
his strongest moral sentences is aimed at envy, from which he suffered
much in his own life, and against which he guarded with a curious
amount of caution. His own family grudged the distinction which his
talents gained for him, and a dark story is told of a secret attempt
made by them to assassinate him through his servants. Alberti met
these ignoble jealousies with a stately calm and a sweet dignity of
demeanour, never condescending to accuse his relatives, never seeking
to retaliate, but acting always for the honour of his illustrious
house. In the same spirit of generosity he refused to enter into wordy
warfare with detractors and calumniators, sparing the reputation even
of his worst enemy when chance had placed him in his power. This
moderation both of speech and conduct was especially distinguished in
an age which tolerated the fierce invectives of Filelfo, and applauded
the vindictive courage of Cellini. To money Alberti showed a calm
indifference. He committed his property to his friends and shared with
them in common. Nor was he less careless about vulgar fame, spending
far more pains in the invention of machinery and the discovery of
laws, than in their publication to the world. His service was to
knowledge, not to glory. Self-control was another of his eminent
qualities. With the natural impetuosity of a large heart, and the
vivacity of a trained athlete, he yet never allowed himself to be
subdued by anger or by sensual impulses, but took pains to preserve
his character unstained and dignified before the eyes of men. A story
