In this paper, we examine the brief history of the ring of four almonds regarding Mesopotamian mathematics, and present reasons why the Omar Khayyam's triangle, a special right triangle in a ring of four almonds, was essential for artisans due to its unique pattern. We presume that the ring of four almonds originated from a point symmetry figure given two concentric squares used in the proto-Sumerian Jemdet Nasr period (approximately 3000 B.C.) and a square halfway between two given concentric squares used during the time of the Old Akkadian period (2340-2200 B.C.) and the Old Babylonian age (2000-1600 B.C.). Artisans tried to create a new intricate pattern as almonds and 6-pointed stars by subdividing right triangles in the pattern of the popular altered Old Akkadian square band at the time. Therefore, artisans needed the Omar Khayyam's triangle, whose hypotenuse equals the sum of the short side and the perpendicular to the hypotenuse. We presume that artisans asked mathematicians how to construct the Omar Khayyam's triangle at a meeting between artisans and mathematicians in Isfahan. The construction of Omar Khayyam's triangle requires solving an irreducible cubic polynomial. Omar Khayyam was the first to classify equations of integer polynomials of degree up to three and then proceeded to solve all types of cubic equations by means of intersections of conic sections. Omar Khayyam's triangle gave practical meaning to the type of cubic equation $x^3+bx=cx^2+a$. The work of Omar Khayyam was completed by Descartes in the 17th century.

The Epic of Gilgamesh drew heavily upon Mesopotamian literary tradition. Sin-leqe-uninni, the editor of Standard Version of the Epic of Gilgamesh in 13th century B.C.E. adopted the Old Babylonian version as well as older Sumerian tales about Gilgamesh. He also was very successful by extensive use of materials and literary forms originally unrelated to Gilgamesh. The epic opens with a standard type of hymnic-epic prologue. This study lens a measure of vindication to the theoretical approach by which Morris Jastrow recognized the diversity of the sources, which underlies the epic and succeeded in identifying some of them. Thanks to the ample documentation available for the literary development of the epic, we can trace the steps which its author and editors took with the result that the epic inspires fears and aspirations for more than three thousand years.

본 연구에서는 2015 초등 수학 교과서 및 지도서에서 보완이 필요한 수학사 기술내용을 파악하고 이에 대한 보완방안을 제안하고자 한다. 이를 위해 2015 초등 수학 교과서 및 지도서 24종에 대한 문헌연구를 진행하였다. 연구의 결과는 다음과 같다. 2015 초등 수학 교과서 및 지도서에서 보완이 필요한 주제는 총 10가지 주제로 '고대 이집트인의 산술', '고대 이집트 수학 교과서 A'h-mosè 파피루스', '메소포타미아 고아카디안 사각띠', '메소포타미아 고바빌로니아인과 각도', '고대 이집트인과 고바빌로니아인의 원주율', '고대 이집트인과 고바빌로니아인의 $\sqrt{2}$', '이슬람인과 소수', '황금비의 뿌리에 대한 두 가지 주장', 'Archimedes와 실진법', '평면 디자인'이었으며, 이에 대한 구체적인 보완방안을 제안하였다. 이를 통해 기축시대 역사관점을 극복하고 고대 이집트, 고바빌로니아, 고대 그리스와 헬레니즘, 중앙아시아(이슬람 1000년), 유럽으로의 수학문화 전이를 인정하고 수용하게 되기를 기대한다.
