From further back than you suggest; but if an historical artefact survives, it survives until the times you suggest...

A large photograph of a church's stained-glass window: four saints can be seen, their vestments have thick, black borders.
Next to it, an ancient book, collecting fragments and pages from ancient ecclesiastical texts; with care the four saints above can be correlated with a certain English abbey, and the latin phrases: '-they have upon their vestments words that which no man knoweth', and '-there is a stone with seven stars'.

A small bronze tube about four inches long, quite full of beach sand.
When cleaned, there can be read 'Fle, Fla, Flu, Fle' on one side, and the latin phrase easily translated as 'Who is this who is coming?' on the other.
Label: 'Aldeburgh, 1936'.

Under constant motion-sensor watch in a sealed room marked 'Danger of Death', a not over-large framed mezzotint of an ordinary English country house; small, three floors. If you should go in and look closely, one of the ground-floor windows can be seen to be open, when the video record shows it wasn't yesterday.
On the back is a torn label '-nningley Hall 1799.'

In a drawer, a soft leather bag containing a beautiful tear-shaped crystal on a string that is apprently made of golden hair. How it is suspended from the string is not obvious. Some people claim to see a whirling blue flame or a waterspout in the centre of it.
Label: 'Alderley Edge, Cheshire, 1959'.
Next to it, a photograph of a rock cliff with the words carved over a horse-trough; 'Thirsty Traveller, drink thy fill, for the water falls, by the wizard's will'.

A tall cupboard/closet containing a chipped white teacup with a pearl-pattern rim, a blocky stone about a foot across, a rusty sword that looks like a toy, and a stick about five feet long with an old bronze knife on the end.
No label.

A puzzle for the latin scholar: a strong wooden box marked 'hedge maze markers', containing 25 Square cobblestones, each one Marked with a letter: AAADEEEIIIMNNNOOPRRRRSSTT.
Label: '1750?'

In a securely-locked glass case, a slip of paper about half-an-inch by ten inches, with a line of unusual runes, similar to norse.
Label: 'Do NOT Touch'.
