Moroccan Geometry: S4: 8-fold with scissors, tessellated

8-fold with Scissors (Mtemen bil Maqoussa) متمن بل مقوسرة


The basic construction consists of 5 circles arranged in an X pattern. This yields an 8-fold pattern centered on a "reverse seal of solomon" with 4 sets of scissors pointing inward, alternating with 4 arrows pointing outward. 

Alternatively, the pattern can be shifted diagonally by half of a panel, in which case the construction is based on 4 circles arranged in a square, and each circle touching another circle radiating from its diagnonal. This yields a pattern with a seal of Solomon at its center, surrounded by 4 scissors pointing outward, alternating with 4 "mgelsa", or seats.

In either pattern, each circle is divided into eighths, with marks along the horizontal, vertical, and both diagonal axes. All construction lines pass through these marks.



To tessellate the pattern on a 12"x18" page, you will repeat the 5 crossed circles six times. 


The original class pattern consists of 4 circles arranged adjacently in a square, with another circle adjacent to each diagonal. This may be seen in full twice in the tessellation, and this pattern overlaps itself along the side circles.



If 8 is the top mark on each circle, then 1 is the first mark in the clockwise direction, etc. Begin the construction lines on the diagonal axes by connecting points 6 to 4 and 8 to 2 moving from NW to SE, then on the SW to NE axis, points 6 to 8 and 4 to 2. Extend the lines beyond the frame ONLY if they connect a similar set of points on the adjacent circles. Otherwise, extend the line only to the edge of the 5-circle frame, as illustrated below, where the yellow lines extend outside the basic frame while the purple lines do not.



Now connect the points 7 to 5 and 1 to 3 on the vertical axis, and points 7 to 1 and 5 to 3 on the horizontal axis. These lines may be extended over the length and width of the entire page.



Note the points where each vertical or horizontal meets a diagonal.  Connect the opposite points along the horizontal, vertical, and diagonal axes. Once again, the horizontal and vertical lines will extend the entire page, while some of the diagonals will not. Each circle will have 16 lines passing through it.



Beginning with one of the central clusters of 4 circles, highlight the pattern in pencil, first with the seal of Solomon, then working outward from there.

Thin-crust pizza

I had a 20-year career in telecommunications engineering in my thirties and forties, at times working alongside an Italian-American guy from New York. Bob had deeply set eyes and a hangdog look, at odds with his pleasant manner. On Fridays, he'd show up at the office with a homemade pizza that he called his "garbage pie”—baked dough, sauce, cheese, and whatever leftovers were in his fridge. Pizza is a dish of humble origins, so when it became known that Margherita of Savoy, the first queen of unified Italy, loved pizza and often asked her kitchen staff to prepare it, the dish was elevated to an honored position, and the Pizza Margherita, in the colors of the Italian flag, was named for her. On a personal level, some things   about this dish are inviolable.   I’ll never let barbecued chicken or sliced pineapple  near it. Or broccolli or cannned tuna. That being said, it’s probably the most bastardized, personalized dish in the world, but I keep it simple.  I once...

Moroccan Seafood Bastilla

Moroccan seafood bastilla is a rich mixture of shrimp, calamari, and whitefish, seasoned with herbs and spices, fluffed out with cellophane noodles, and wrapped in "warqa" (Arabic word for "paper") a Moroccan filo dough made fresh daily in the souks, the large marketplaces filled with independent vendors that are in any Moroccan city of any size. In coastal cities like Essaouira and Agadir, bastilla is available in the souks in individual serving sizes .   But wherever I tried it, it seemed a little underwhelming. There was a potentially great dish there, but the flavors were muted.  It seemed strange that the seafood bastilla should be as bland as it was. After all, its cousin, chicken bastilla, albeit with a much different set of ingredients and spice mixture, is such a special occasion dish that I'd ask Nabila, our housekeeper in Fes, to make it whenever there were guests.  The typical seafood bastilla contained ingredients that I felt blunted the flavor of t...

Moroccan Geometry: S9 Master Class: 10-fold with the Eye of the Sun from Bou Inania Medersa, Fez

  Adv S9 Master Class: 10-fold with the eye of the sun, from Bou Inania Medersa, Fes Part A: Draw the main circle and subdivide it into tenths. This 10-fold design is based on 2 concentric circles. These two fully contain the 4 central shapes. 10 other overlapping circles whose centers are outside of the outer circle complete and contain the remaining shapes. The first of the 2 concentric circles to be drawn is the outer one 1.  We want the finished drawing to fit with 5 mm margins above and below. The ratio of the circle's radius, A, to the distance between the center and the outer point of the pattern, B, is approximately 5 to 7. Using a watercolor paper that is 304mm high, B should be no more than 304mm, minus the 5 mm margins, then divided in half, or 147 mm. So then A, the radius of the main circle, should be about (5/7) x 147 mm, or about 105 mm. Use the usual method of finding the center of the page, draw a circle of the desired radius and quarter the circle with horizo...
