#### Transcript of Islamic Lattice

Islamic Lattice How did Islamic Lattice come into being? Qur'an Islamic Tradition which both take a firm stance on idolarty and the worship of images... Idolatry is defined as the worship of a physical object as a god
~Merriam-Webster dictionary So no animals and humans in art as for as the early Islamic religious leaders were concerned. This is not so today in modern Islamic art. by Siddiqua Shahnawaz Although there are examples of geometric ornamentation in the Byzantine and Sasanian empires it reached its pinnacle in the Islamic world...... this geometric ornamentation became known as..... Islamice Lattice influenced indirectly by
Islamic mathematicians scientists astronomers Created with.. Ruler and compass the "circle" due to refinements of the
compass by Arabic astronomers is the... Foundation of... is made up of a small number of geometric
shapes that are repeated to form patterns. The circle, square, and the straight line form
the basis for the patterns. stressed.. unity logic order Patterns are based on three
types of grids... Square triangle hexagon So how is Islamic Lattice created? First a type of grid is chosen. Second a circle is drawn at each vertex of the
grid. Next, erase the grid and then place equally
placed dots around each circle. Next draw lines bouncing from one circle to another that looks similar to billards on a table with obstacles. The angle of incidence must equal angle of reflection. In other words
the angle the line strikes a circle, that line must leave at the same angle. The lines are then thickened and woven in alternating
underpasses and overpasses. Lastly erase the original circles. So what effects Islamic Lattice design? It is... which grid you use the size of you circle how many dots on the circle
(the more dots the more complex the pattern) the initial angle of incidence drawn
(when you connect your first dots
with a line) overpasses and under passes is a tiling or tessellation.... examples are found in... furniture Rugs Wooden or Stone Screens tiled walls and floors know as "Jali" and finally it might look something like this one theory is from Here are some examples...
