English description

This multi-cache consists of four stages, all of which lie inside the city of Graz. It furthermore requires a preparatory phase to determine the coordinates of the first stage. The first three stages are intermediate stages, only at the fourth stage a cache container is to be found.

This cache bears some similarities with my cache Artistical Variations. It is again a cache where the main idea is to lead you to places in Graz which are not that well-known, but which I regard as interesting, both from the architectural point of view and from the historical point of view. The cache will probably challenge you more on the intellectual side than on the physical side.

Important information: (Please read this part before you start your hunt!)
  • The starting coordinates given for this cache are fictive ones and are of no significance.
  • This cache is not suited if you are eager for a quick and cheap find. It is also not well-suited for short-term visitors of Graz due to the time it takes.
  • Since this cache requires quite some effort, I have set up a virtual cache, the A Walk to the Past - Virtual Bonus Cache. This virtual cache is closely connected to this cache and should serve both as a reward and as a source of motivation for doing this cache. The virtual cache can only be done after having successfully completed this cache. If you are interested into doing the virtual cache, do not forget to read the information sheet in the cache, and to write down the two numbers which are given there.
  • Those cachers who complete this cache in one go (i.e., without returning home between the stages) deserve special credit.
  • The cache hunt will lead you to some buildings with restricted opening times. It is, however, not necessary to enter any of these buildings for the sake of the cache hunt. Visits of the buildings are strongly recommended, but separate visits not connected to geocaching activities seem to be more meaningful and appropriate.
  • Some of the historical background associated with the places to which this cache will lead you is serious and sad. For that reason, I underwent a special effort to set up this cache in a manner which avoids any disrespectful treatment of the matter.
  • Since the stages of this multi-cache are not always close to each other, but finding a suitable place to leave a car might be quite hard, it is very recommendable to do this cache by bicycle.
  • It is recommendable to take a map of Graz with you. Good shoes might be an asset at the final stage.
  • Note that upper and lower case variables, like a and A, have to be distinguished! Upper-case variables are only used temporarily and are not needed again at later stages.
  • To help you not to get lost in some sort of chaos, I am providing two tables (see Table for the variables and Table for the coordinates of the stages).
  • The set of trading items for this cache is (strictly) restricted to coins which are not any longer valid means of payment.

Stage 0: At a place of your choice

Stage 1 will lead you to a church (let us call it C for notational convenience) which is located in one of the inner districts of Graz (i.e., in the first six). Below some information on the church C is given, but not its name. You need to deal with the following questions and tasks.

Question 1: In the church C an interesting sacral work of art can be found which depicts two cruel dictators amidst a religious scenery. Find out which church is meant. (You will need to visit it at Stage 1.)

Question 2: Find out the name of the artist who created the work of art referred to above. Let us call him Mr U.
  • A: The number which is obtained by applying the following procedure to the artist's first name: Replace each letter by the digit which is associated with this letter on the key-pad of portable phones.
  • B: The number which is obtained from the last name of Mr U by proceeding in the same way as for his first name.
  • a: The absolute value of the difference of the numbers A and B.
  • b: The iterated cross-foot of the year in which the work of art has been finished. (I.e., sum up all digits of the year, and repeat this procedure with the obtained result iteratively until you end up with a result with a single digit. For example, the iterated cross-foot of 987654 is 3 with 39 and 12 being the results of the intermediate calculations.)
  • c: The number of letters of the name of the city in which Mr U died. (Note: If you come across contradictory information, take the city which lies in the country of which Mr U was a citizen at the time of his death.)
Question 3: Mr U has been invited to become a member of a famous organization of German artists at quite a young age.
  • d: The number of letters of the full name of this organization (two words).
Question 4: Find out the name of the artist who acted as president of the organization referred to above at the time when Mr U became its member. Let us call this artist Mr V.
  • e: The number of letters of the first name of Mr V.
Question 5: The last name of Mr V is also the name of a city. There exist parts of the Bible in the names of which this city plays a role.
  • f: The number of parts of the Bible which fit the above description. (Note that only those parts whose existence is known for sure and which are part of today's editions of the Bible are to be counted.)

Stage 1: At Church C

Go to church C and find a plaque at the outside of the building.

Question 6:
  • g: The earliest year mentioned on the plaque.
Question 7: The text on the plaque contains the names of two artists who created works that can be found inside the church. Here we are interested into the one who lived earlier. Let us call him Mr W.
  • h: The cross-foot (=sum of digits) of the number corresponding to the first letter of the first name of Mr W via the code A=1, B=2, ..., Z=26.
  • H: The number of letters of the first name of Mr W.
Question 8:
  • i: Number of horizontal bars of the cross at the top of the tower. (Do not take into account the different manners that exist to create such a cross, just the appearance the cross creates when viewed from far away.)

Question 9:
  • j: The first digit after the comma of the decimal number which represents the minutes of the longitude of the location of Stage 1.

Some calculations:
  • P = (b*c-30)*(d-e-h)
  • Q = a-g+P
  • R = e^3*f^3
  • p = Q/R
  • q = (b+d)
  • D = (g-q/2+H-e)
  • F=d*i
  • r=D/F

Stage 2: N 47° p', E 015° q.0r'.

You will find yourself close to a building which is an interesting mixture of old and new. Nearby you will find an information plaque providing some facts about a person who spent some years in Graz. Let us call him Mr Z.

Question 10: Determine the (d-b)-th word of the text on the plaque. This word arises in the title of several works of art. Here we are interested into the most famous among those. Who created it and in which city can it be found today?
  • m: The number of letters in the artist's name (the commonly used name, not the full one) until the first A occurs (the A is not to be included into the counting).
  • n: Find the name of the river flowing through the city you have just obtained above. Associate each of the letters arising in the river's name with the digit which corresponds to it on the key-map of a portable phone. Let n be the largest digit obtained in this manner.
Question 11: The plaque tells you the cities where Mr Z was born and died, respectively. You need to find out the countries in which these cities lie today (as of 2003). Determine the country codes which identify motorized vehicles from these countries.
  • s: Translate the country codes into numbers via the key-pad of a portable phone and subtract the smaller number from the larger one. Call the result s.
Question 12: The plaque tells you the cities in which Mr Z has studied until earning his Ph.D. degree. Among these cities, there is one where Olympic Summer Games have taken place.
  • t: The cross-foot (=sum of digits) of the year in which the Olympic Games referred to above took place.
Question 13: ) Now walk around the building (if this is not possible, use Question 13b instead). Interesting, isn't it? At the outside of the building you can somewhere find two numbers separated by a slash.
  • k: The number before the slash.
  • l: The number after the slash.
Question 13b: (Workaround for Question 13) Watch out for two signs which contain an arrow and mention the name of a company.
  • l: The position of the German umlaut letter in the company name (full name, only letters count).
  • k: k=l*(n+1)
Question 14: Determine the bridge over the river Mur which is closest to Stage 2.
  • o: Number which is associated with the first letter of the name of the bridge via the code (A=1, B=2, ...).

Some more calculations:
  • u = s-t-k/l-n+o
  • v = (d+s)/2

Stage 3: N 47° 0e.cmu', E 015° v.nuj'.

You find yourself close to a crossing. Starting from here you need in any case to continue on foot. Take the path leading to the south-east and follow it until you arrive at a large building. Watch out for a plaque at the outside of the building. The plaque honors two men.

Comment June 2020: Currently the building is under renovation and the plage is covered. However it should be possible to decipher two numbers at the bottom of the plaque which will allow you to answer the first question below. For the second question, mobile internet access should do the job if you are not familiar with the area.

Question 15:
  • w: The number of years one of the two men died later than the other one (Disregard the months in which they died - take into account only the years of their death.)
  • x: The overall number of letters of the name of the place (two words) which has been founded (begründet in German) by one of the two men.

Some final calculations:
  • y = (w+7)/(x^2)
  • Z = k-6*l+j*o/2
  • z = Z/(x^3)

Calculation of the coordinates of Stage 4:

The coordinates of Stage 4 are obtained from Stage 3 by the following procedure:
  • Subtract y from the minutes of the latitude corresponding to Stage 3.
  • Add z to the minutes of the longitude corresponding to Stage 3.
  • The remaining parts of the coordinates are the same as for Stage 3.

Stage 4: Coordinates as computed above.

Since September 2014 you can choose between the following two options to reach the final.

Option 1: (Letterbox like clues, following the original idea of the cache dating back to 2003)
You will find yourself close to an object to which a sign with w+3 letters is attached. Follow the path which passes by the object downhill until you arrive at a crossing with another trail. At this crossing turn left and follow the path downhill. Soon a small path leads into a ditch to your right. Turn right into this path and after a few steps start to climb up the slope to your left. Watch out for an eye-catching stump of a former large tree with multiple stems. There you will find the cache container. Rehide it well.

Option 2 (the more boring one):
If you fail to find the cache with the above clues or absolutely want to use coordinates (be warned the reception is not very good), you can calculate coordinates for the final by the following offset from the coordinates of Stage 3:
  • N: -(w+7)*x/1000'
  • E: +(w+5)*x/1000'

The cache container is a small lock and lock container and contains no trading items. Good luck!

Please note the following:
  • For approaching the hiding location you can stay on paths, except for the very last part for which good shoes are recommend (the T=2.5* rating applies to the final).
  • You are asked to be very careful not to disclose the hiding place and to leave the hiding place as you found it. Special care is neeeded on sunny days when many walkers are around.
  • When logging the cache, please avoid to add any form of spoilers to your log entry, regardless of whether encrypted or not. (It took me quite some effort to formulate the questions in a way that they are concise, but do not give away any information unintentionally.)

[EN:] Currently the building at Stage 3 is under renovation and the plage is covered. However it should be possible to proceed as described by isenfriesen whom I thank for notifying me about the issue.

I temporarily added a comment to the description of Stage 3 which suggests the following approach for the time being: Try to decipher two numbers at the bottom of the plaque which will allow you to answer the first question below. For the second question, mobile internet access should do the job if you are not familiar with the area.

[DE:] Zur Zeit wird das Gebaeude bei Station 3 renoviert und die Tafel ist mit Plastikfolie bedeckt. Es sollte jedoch moeglich sein, so wie von isenfriesen, der ich für die Mitteilung des Problems danke, vorzugehen.

Ich habe einstweilen einen Kommentar in die Stationsbeschreibung eingefuegt: Versuche 2 Zahlen im rechten unteren Bereich zu entziffern. Diese fuehren zur Antwort auf die erste Frage. Die zweite laesst sich via Internet beantworten falls sich die Antwort nicht ohnedies aufgrund von Ortskenntnis ergibt.

trovata The geocache is in good or acceptable condition. Raccomandata 14. ottobre 2019 Euni ha trovato la geocache

Vor einem Jahr hatte ich "Aristical Variations" absolviert und es entstand bei mir der Wunsch, auch "A Walk to the Past" zu machen. Da ich immer nur für wenige - diesmal vier Tage - in Graz bin, habe ich die Warnung zur Kenntnis genommen, dass es kein Cache für einen kurzen Besuch ist. Nein, ich habe diesen Cache nicht in einem Ritt ohne Benutzung des Internets machen können. Ein erster Versuch im April scheiterte, ich landete vollkommen falsch in der Nähe vom Volkshaus. Dann verabschiedete sich noch das Handy (Totalschaden, Hauptplatine kaputt, Neukauf). Am Freitag noch einmal den Ort an Stage 1 aufgesucht und wegen zwei oder drei Schussligkeitsfehlern wieder am Volkshaus gelandet. Die Ownerin wurde kontaktiert und teilte mir mit, dass ich ein kursiv geschriebenes Wort übersehen habe und Länge und Breite verwechselt habe. Nachdem diese Fehler ausgemerzt waren, landete ich an einem Ort, der mir von früheren Grazbesuchen und einem ebenfalls empfehlenswerten Cache schon bekannt war. Ich ermittelte die Koordinaten von Stage 3 und war erstaunt, wie weit diese entfernt ist. Schöner Spaziergang an der Mur. Wirklich ein sehenswerter Ort, dann war es nur noch eine Frage der Zeit, bis ich die Dose gefunden habe.
Ich bedanke mich für den bemerkenswerten Cache mit einer Empfehlung und bedanke mich nochmals für die schnelle Hilfe der Ownerin.

heute reisten wir nach graz um diesen aufwändigen mystery zu absolvieren. unser eigentliches ziel war aber sein dazugehöriges bonusdoserl!
obwohl schon viel nachforschungsarbeit im vorfeld erledigt wurde, erreichten wir erst spätabends die finallocation. das doserl konnten wir dort aber schnell entdecken - zu dieser uhrzeit völlig muggelfrei.
für ro war dieser spaziergang ein besonderes erlebnis - er konnte viele kindheitserinnerungen auffrischen - auch die finallocation war oft ein ausflugsziel mit seinen großeltern!
danke für diesen mystery - das thema hat uns auch im nachhinein sehr beschäftigt - und für die rasche logfreigabe fürs bonusdoserl. möge es noch lange weiterleben als fast letztes seiner art in österreich! Cool
