The first, oldest, and most common of these similes, all of which can be applied literally to persons or, more often today, to issues, involves doornail, dating from about 1350. Its meaning is disputed but most likely it referred to the costly metal nails hammered into the outer doors of the wealthy (most people used the much cheaper wooden pegs), which were clinched on the inside of the door and therefore were "dead," that is, could not be used again. Dead as a herring dates from the 16th century and no doubt alludes to the bad smell this dead fish gives off, making its death quite obvious. Dead as a dodo, referring to the extinct bird, dates from the early 1900s.

It is not clear why these nails should be described as `dead'.

dead as a (or the) dodo

1 no longer alive. 2 no longer effective, valid, or interesting. informal
The name dodo comes from Portuguese duodo meaning ‘simpleton’. It was applied to the large flightless bird of Mauritius because the bird had no fear of man and so was easily killed, being quickly wiped out by visiting European sailors. The dodo's fate has made it proverbial for something that is long dead and the name has been used metaphorically for an old-fashioned, stupid, or unenlightened person since the 19th century.
