The idiomatic expression "a thing of the past" signifies that something no longer exists, is no longer practiced, or is no longer relevant or important. It implies that something has become outdated, obsolete, or has disappeared from current usage or reality.
While the individual words have literal meanings, the phrase as a whole carries a figurative weight. It's about the idea of something belonging to a bygone era rather than a literal object being physically located in the past.
There's no specific documented origin for this phrase. It likely evolved naturally through everyday language use. The register is generally neutral, leaning slightly towards informal.
The phrase "a thing of the past" is quite flexible. It can be modified with adverbs (e.g., "almost a thing of the past"), negated (e.g., "not a thing of the past yet "), and used in questions (e.g., "Is it a thing of the past?"). You can also change the subject preceding the phrase (e.g., "That idea is a thing of the past.").
Over-literal use can sound unnatural. For example, saying "My grandmother's antique clock is a thing of the past" sounds odd because while the clock is old, that's not the idiomatic meaning. It's better suited to describe something that's no longer in common use or practice, not merely old.

No, the phrase is almost always used figuratively. While the individual words have literal meanings, the expression itself refers to something's obsolescence or irrelevance, not its physical location in time. It's about the idea of something being gone.
Both phrases suggest something is old and irrelevant, but "ancient history" is more informal and often implies something is very old and no longer worth discussing. "A thing of the past" is more neutral and can apply to things that disappeared more recently.
Be mindful of the register and context. Avoid using it in highly formal writing where a more precise term might be preferred. Also, remember it describes something that is no longer relevant or in use, not just something that is old. Make sure the subject is something that has genuinely faded away or become obsolete.
