Origin of handwriting
An ordinary note in his [Horace Greeley's] handwriting is said to have been used for a long time as a railroad pass, then as a servant's recommendation, and finally taken to a drug-store as a doctor's prescription. ["Frank Leslie's Magazine," August 1884]
handwriting on the wall
Also, writing on the wall. A warning or presentiment of danger, as in The company was losing money, and seeing the handwriting on the wall, she started to look for another job. This expression comes from the Bible (Daniel 5:5–31), in which the prophet interprets some mysterious writing that a disembodied hand has inscribed on the palace wall, telling King Belshazzar that he will be overthrown.
