where does the clinking of glasses come from
Toast (honor) According to various apocryphal stories, the custom of touching glasses evolved from concerns about poisoning. By one account, clinking glasses together would cause each drink to spill over into the others' (though there is no real evidence for such an origin).[2] According to other stories, the word toast became associated with the custom in the 17th century, based on a custom of flavoring drinks with spiced toast. The word originally referred to the lady in whose honor the drink was proposed, her name being seen as figuratively flavoring the drink.[3][4] The International Handbook on Alcohol and Culture says toasting "is probably a secular vestige of ancient sacrificial libations in which a sacred liquid was offered to the gods: blood or wine in exchange for a wish, a prayer summarized in the words 'long life!' or 'to your health!'"[5]
Stained glass Evidence of stained glass windows in churches and monasteries in Britain can be found as early as the 7th century. The earliest known reference dates from 675 AD when Benedict Biscop imported workmen from France to glaze the windows of the monastery of St Peter which he was building at Monkwearmouth. Hundreds of pieces of coloured glass and lead, dating back to the late 7th century, have been discovered here and at Jarrow.[8]
