- The "Marine" scene from The Apotheosis of Washington has the Roman goddess Venus emerging from the ocean as she did in the time of ancient Greece so she can complete her godly duties... to wire transatlantic telegram cables. Behind her and Neptune's mighty horsemen, you can see a smoke-stacked industrial factory.
- Much religious art from The Renaissance on. This had a solid Real World justification, though. Religious paintings, especially on the walls of churches were designed for the masses, and the goal was not to depict a scene exactly as it was, but to tell the story for everyone to understand. Through the use of contemporary clothing, armor, and styles, even the common people could instantly recognize "that's a soldier, that's a fisherman, that's a shepherd, that's a tax collector, that's a nobleman, that's a commoner" etc. instead of "WTF are those people in those silly clothes?"
- This got completely out of hand by the 18th and 19th centuries, when both Pontius Pilate and Herod were depicted in extravagant Persian-type robes.
- Historians can and do judge when forks reached different parts of Europe by looking for them in paintings of the Last Supper. Judging military equipment is a little trickier, as you can never quite predict when someone's depicting the cutting edge and when he's depicting a suitably "old-fashioned" type of armor, but that tends to be well-attested elsewhere.
- This astronaut on a cathedral built in 1102 is another example.
- An entire style of painting, the classical landscape, was dedicated to this. It incorporated classical, medieval, and contemporary architecture while showing biblical or historical characters.
- The Big Finish Doctor Who audio drama Invaders from Mars actually has some deliberate anachronisms, such as a character saying there was 49 states in 1938, when there was only 48, and someone repeatedly referencing the CIA when it wouldn't be founded until nine years later. This was due to the influence of "anti-time." Other mistakes, however, were less deliberate, like Orson Welles' The War of the Worlds broadcast being on October 31 instead of October 30.
- Medieval Madness plays the absurdity of medieval pinball for laughs throughout the game.
Rioting Peasant: "They've taken our pinball machines!"
- Inadvertently invoked by Eight Ball Champ, which mixes an Edwardian Era theme with computerized sound effects and a Machine Monotone voice.
