DETECTIVES

ERASMUS+ PROJECT

OPEN the envelope Click on the stamp

You have received a misterious leter

Look inside and read carefully

You have probably known that the great deal of Leonardo da Vinci’s sketches and diary pages include mirror writing. There are naturally a host of theories why Leonardo used mirror writing. Some claim that Leonardo wanted to hide his texts and studies and used mirror writing as cipher....

Dear students, After two years of the STEAM like Leonardo project you are enriched of knowledge, experience and spirit of the Great Renaissance Man. We are sure that you are able to successfully complete the missions. Remember to be careful, collaborative and patient. Your task is to find the hidden clues - usually they are invisible, so use your computer mouse to search the space.Start right now and find the first task here.

Mona Lisa is probably one of Leonardo da Vinci’s one of the most iconic works. This figure of a woman, dressed in the Florentine fashion of her day and seated in a visionary, mountainous landscape, is a remarkable instance of Leonardo's sfumato technique of soft, heavily shaded modeling. The painting was among the first portraits to depict the sitter before an imaginary landscape and Leonardo was one of the first painters to use ..........(what?)Look carefully, here you will find the hidden message which need to be decoded.

If you found the message and don't know what it means come back to the room and search for a clue.

The Caesar Cipher technique is one of the earliest and simplest method of encryption technique. It’s simply a type of substitution cipher, i.e., each letter of a given text is replaced by a letter some fixed number of positions down the alphabet. For example with a shift of 3, A would be replaced by D, B would become F, and so on. The method is apparently named after Julius Caesar, who apparently used it to communicate with his officials.Use this cipher to decode the message.

Congratulations!In this room you can find some Leonardo's sketches. They come from different Codexes. One of them reveals you some secrets. Study them carefully to find the hidden hint. Good luck!

A Polybius Square is a table that allows us to convert letters into numbers.To decrypt the message, you need to use this table. Each letter is made up of two numbers, the first being the row it is in and the second being the column it is in. For example the letter 'H' would be described with 23. It is the third letter in the second row.

The skull sectioned is a drawing by Leonardo da Vinci and, dating from 1489, one of his earliest human anatomical studies. That year, for the first time, he had acquired a human skull.Alongside are careful drawings of teeth with their roots shown and numbered. Inhis notes Leonardo gives the number and position of all the teeth.Leonardo was probably the first to describe the human dental formula.Arrangement of the teeth and dental formula of one half of the mouth.The morse code explains you what to do with these numbers

Return

Leonardo’s diagrams and sketches of the skull, skeleton, muscles and major organs fill countless notebooks while his theories on how they function fill many more pages.But it was the heart that appeared to particularly fire his interest, from 1507 onwards, when he had reached his 50s. He found that the heart had four chambers and it connected the pulse in the wrist with the contraction of the left ventricle. Leonardo also looked closely at the actions of the heart valves and the flow of blood through them. In his drawings, he used his knowledge of fluids, weights, levers and engineering to try to understand how the heart functions. Leonardo produced the first known description of the heart disorder.After decoding the name of the illnesscount amountof(basic) vowels- remember it - it will be needed.

Return

As you know Leonardo recorded his thoughts in notebooks. He filled multiple codexes with sketches, ideas, inventions, and more over the course of his life.You could find here a message with Leonardo's famous mirror writing: the handwriting goes from right to left, and the only way to read it is by looking at the text througha mirror.Try to read it off and ADD all numbers - a mirrow or a mobile can hel you - remember the sum.

Well done!Here you can see another sketches. Leonardo was a keen lover of the invention, painting, and sculpting, as well as an enthusiastic scientist whose interests included engineering and mathematics. Search for another clue and move to the last room.

Leonardo was well aware of the critical role of mathematics in the formulation of scientific ideas and in the recording and evaluation of experiments.A dodecahedron is a solid shape that has twelve surfaces. Each face is a pentagon (has five edges). In total there are twenty corners (also called vertices) and thirty edges altogether. A dodecahedron which looks exactly the same from all faces.No clue here.

Leonardo da Vinci's drawing of thecuboctahedron

Leonardo Da Vinci’s knowledge of mathematics did not take off until he was in his early forties. Much of his education came through gaining knowledge by following an ongoing program of self-study. In his forties, he studied Mathematics with the Franciscan friar named Lucca Pacioli. Da Vinci’s interest in geometric shapes such as the polyhedra are visible in the many sketches scattered throughout his drawings. The Platonic solids and six other sets of solids which can be obtained from the Platonic Solids were drawn by Leonardo. Those irregular solids are get by cutting off the corners of the Platonic solids. All faces are regular polygons, but there is more than one polygon in a particular solid, and all vertices are identical.

Portrait of Ginevra de' Benci

The Virgin and Child with Saint Anne

“Lady with an Ermine” is a Leonardo da Vinci’s painting, from around 1489-1490. The portrait is a great example of individual Leonardo’s painting style and his unique light and shadow crossing. The Lady With An Ermine' came into Polish hands in 1800, after it was bought by the young Prince Adam Czartoryski (later a hero in the fight for Polish independence) during his tour of Italy. From May 2017, the painting is displayed in the main building of the National Museum (where)
