]]>Dear Sam,

it is fine that you share your labyrinth experiences with children here on the blog.

They generally have a good feeling for what a labyrinth can be.

Thank you

I like starting by asking what is a labyrinth. Generally the kids rather bring in the ‘maze’ concept, i.e. a winding set of trails with choices and dead-ends.

I then explain that the word ‘labyrinth’ generally refers to a very long path winding from the edge of a rather small place to its center, indeed a dead end.

Then I ask what would be the simplest figure that packs a straight line say 150m long (that would require a long stretch of land) into a place say 10m across), and generally it doesn’t take long to hear, after the word circle or square (that would still be too lage to fit in) the word (Archimedes or

arithmetic) ‘spiral’ which indeed is a ‘protolabyrinth’ much older than about the 5000 years ago that saw the birth of the Cretan labyrinth. The length of a spiral being a good approximation of an equally densely packed Cretan.

Then follows the story of the Cretan labyrinth : I ask the children to close their eyes and imagine to be at the sea shore at low tide, when the beach is an ideal place to draw labyrinths. Starting with the usual +-sign (two perpendicular lines 2m long crossing in the middle), 4 points in the corners (of a square built on the +-sign as its medians) and a (diameter 1m) circle divided in four where each quarter fits between a point and the closest edges of the +, the obtained figure being the ‘seed’ of the Cretan labyrinth.

I select 8 children ranked by size, the little 3 years old is placed on the upper end of the + and the others are placed to the left; half a meter apart from each other to the point close to the bottom edge of the +. I show there are exactly 8 points awaiting them at the other side.

Then I first help the little kid drawing a small half circle from the top of the + where she stands to the end of the quarter circle to the right. After that all the other kids have to do is to follow the previous kid at exactly half a meter distance, and soon enough the labyrinth is in place and all the children can get inside, between the ‘walls’ they have just drawn, discovering the center is too small to hold them all… Etc…

Kind regards,

Sam
