The word “ladder” can be traced back to the Old English word “hlæder” which roughly translated means “something that slopes”. It is estimated that ladders as we know them have been in use for over 10,000 years. Cave paintings from the Mesolithic era in the Spider Caves in Valencia, Spain were discovered picturing two people with a long, rickety ladder, thought to be made out of woven grass, heading towards a tree with a bees nest in it, in order to collect some honey. As time moved on and tools progressed, we begin to see examples of wooden ladders and in medieval times these were used to help storm a castle. John Basely from Ohio invented the step ladder in 1862; he put a hinge in between two ladder sides to enable it to be stored more easily.
This would have been stored hanging on the underside of the groom’s seat in the coach and would have been used for climbing to the top level of a coach and then probably a high top car.
Ladders of this type are scarce making this set desirable for collectors though it also makes for a novel wall decoration or perhaps helping you reach for the next novel.
