Albrecht Dürer's "Melencolia I" contains numerous mathematical and philosophical symbols amongst which we can see a magic square, a polyhedron and a sphere. These 3 symbols are partially interpreted in an earlier article.

1514, the date of the engraving, appears in the lower line of the fourth-order magic square. 500 years later, is it possible to create a fourth-order magic torus tribute to Dürer?

In order to write 2014 we can subtract 1 from all the numbers (1 to 16), and thus obtain the zero that cannot be found in

*normal*fourth-order magic squares. After the subtraction, we can use a flattened viewpoint of the basic magic torus T4.177 (group number T4.05.4.12) that displays not only the Frénicle squares n°99 and 618, but also 14 semi-magic squares. The numbers 0 to 15 are repeated beyond the edges of the square in order to represent the toroidal continuity. As the new figures contain the numbers from 0 to (N²-1) instead of 1 to N², their magic constant is 30 instead of 34.A magic torus tribute to Dürer |

Perhaps Dürer hesitated when engraving the left hand side of his square: The number 5 appears to replace a former number 6. It should also be noted that the print detailed in the first version above is, according to The National Gallery of Victoria is

*"the very rare first state."*The reversed number 9 was later corrected in the revised version below. On page 12 of the 1961 Aukland City Art Gallery catalogue "Albrecht DÜRER forty engravings and woodcuts," it is written that*"There are two states - the first where the nine on the numerical table is reversed, the second where the nine is corrected."*The contemplation of the two versions of Dürer's magic square may well remind the reader of the duality of the “De Umbrarum Regis Novum Portis” engravings in Roman Polanski's film "The Ninth Gate." David Fritz Finkelstein has written that*"Dürer's engraving MELENCOLIA I was circulated in two versions not previously distinguished. Besides their conspicuous early Renaissance scientific instruments and tools, they contain numerous apparently unreported concealments whose detection reveals heresies expressed in the work."*Frickelstein believes that the second version of the engraving is the one in which the number 9 is reversed, and suggests that the numerals 9, 6, and 0 are curled serpents.

Dürer's square, (Frénicle n° 175), is one of 8 semi-pandiagonal squares displayed by the semi-pandiagonal torus T4.077 (torus type n° T4.02.2.03). The seven other semi-pandiagonal squares that are displayed by the same "Dürer torus" are the Frénicle index n° 27, 233, 360, 421, 583, 803, and 850. The semi-pandiagonal "Dürer torus" T4.077 also displays 8 semi-magic squares, and is completely covered by 8 sub-magic squares. More details of the fourth-order magic tori can be found in earlier articles such as:

"255 Fourth-Order Magic Tori, and 1 Third-Order Magic Torus," "Table of Fourth-Order Magic Tori," and "Fourth-Order Magic Torus Chart."

A magic torus tribute to Dürer |

Miguel Angel Amela has very kindly authorised me to publish an extraordinary pandiagonal square he created for this anniversary. Again, this is not a

*normal*4x4 square, as the magic constant of all the columns, rows, and diagonals is not 34, but 1514 - the year that Dürer engraved Melencolia I! Miguel has also managed to write 2014 at the centre of the bottom row, in just the same cells that Dürer used to date his square.Miguel Amela's tribute to Dürer : 2014 - 1514 = 500 years. |

The following figure shows a water retention diagram of Miguel Amela's square that was created by Craig Knecht.

Harry White and Craig Knecht have created a giant 196 x 196 water retention magic square that spells the dates 1514 and 2014. Craig Knecht has also devised another 14 x 14 square that honours the 500th anniversary of Durer's famous magic square in Melencolia I. The animation of the latter square can be found at the following link.

Further to the first edition of the present article, on the 21st May 2015, Miguel Angel Amela sent me this very original magic square that he created to celebrate the

**544**^{th}birthday of Albrecht Dürer (1471-1528):Miguel Angel Amela's 544th birthday tribute to Albrecht Dürer, created on 21st May 2015 |

This is not a

*normal*4 x 4 magic square as the magic constant of all the columns, rows, and magic diagonals is not 34, but**544.**Miguel Angel Amela's creation (using the reversed nine version of Dürer's writing style) is the product of the Dürer square integers and 16 (which is the number of integers). Miguel Angel Amela points out that the divisors of**544**are: 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, and 544:
1, 2, 4, 8, and 16 all figure on Dürer's fourth-order magic square.

17 is the total of the complementary numbers 1 and 16, 2 and 15, 3 and 14, etc. on Dürer's square.

32 is either the product of 4 and 2 times 4, or it is twice the number of the integers on Dürer's square.

34 is the magic constant of Dürer's square.

68 is twice the magic constant (2 x 34) of Dürer's square.

136 is 4 times the magic constant (4 x 34), and therefore the total of all the numbers on Dürer's square.

272 is 8 times the magic constant (8 x 34) of Dürer's square.

**544**is 16 times the magic constant (16 x 34) of Dürer's square.

The square includes the numbers 16 (4 to the power of 2), 64 (4 to the power of 3) and 256 (4 to the power of 4) in its corners, and 4x4 magic square enthusiasts will appreciate this subtle wink! Thank you Miguel for allowing me to publish your very original creation!

Lorenzo D. Sisican, Jr.has kindly authorised me to publish two non-normal, but semi-pandiagonal squares that he has created: The first of these squares has a magic constant of 500 in its rows, columns and alternate diagonals (500 years after Melencolia I).

The second of Lorenzo D. Sisican Jr.'s squares is also semi-pandiagonal, and has a magic constant of 500 in its rows, columns and alternate diagonals (500 years after Melencolia I).

The date of the creation of Melencolia I, the year 1514, is obtained by the numbers 151 & 4. The anniversary year 2014 is obtained by the numbers 201 & 4. Melencolia I was created 14 years before Dürer’s death, and the number 14 is also prominent on this square.

ReplyDeletei would like to know why if Durer's magic square has the year at the bottom and hi initials square with 4 and 1 in them respectively why did he not just swap collumns

In Wikipedia , it is stated that “the numbers 1 and 4 at either side of the date correspond respectively to the letters "A" and "D," which are the initials of the artist.”

Deletehttps://en.wikipedia.org/wiki/Magic_square#Albrecht_Dürer's_magic_square

However, as no sources are quoted in Wikipedia, your observation tends to challenge this hypothesis…

All we know for sure is that Albrecht Dürer used several different monograms to sign his works, and that most of these show the “D” or “d” within the “A.” The vertical alignment of his two initials could be interpreted as the wish of the artist to give them an equal emphasis, with no preference for their order. But as it always encompassed the “D” or the “d” in the vertically aligned monograms, the “A” inevitably dominated. Also, for his early drawings prior to 1495, Dürer usually signed with an uppercase “A” in front of a lowercase “d.”

“The Holy Family with the Dragonfly” (circa 1495) is the first engraving on which Dürer placed his monogram.

https://wikivisually.com/wiki/The_Holy_Family_with_the_Dragonfly

One might also wonder why Dürer needed to doubly sign Melencolia I when his single monogram would suffice. If Dürer did not choose the alternative magic square that you suggest, it is probably because he only meant to emphasise the date of his creation.

You have made a good point, and I wish to thank you for your contribution.
