Intro to the table of thirds February 1, 2003 Presented by Bruce C. Friedman Last modified: October 10, 2004. There are numerous tables of hkt divisions on the two tablets from Cairo.  Some appear as many as five times. The following table of one-third of various hkt quantities is found twice on these tablets. Both sets of calculations of thirds are without error. *Note: the more recent changes to this page stem from the superior translation and source images offered by this text: Journal: Archiv Orientalni - The Quarterly Journal of Asian and African Studies, Praha, Czech Republic, 2002 Article: The Wooden Tablets from Cairo: The use of the Grain Unit hk3t in Ancient Egypt. Author: Hana Vymazalova. ANALYSIS OF 1/3 TABLE: Modified and corrected 10/9/04 as per H. Vymazalova. The scribe first determines the value of one-third of five by operating with duplications as follows. *The results of this effort are applied further as one-third of five is used for one-third of five ro [r3]. Five ro [r3] is equivalent to one-sixty-fourth hkts. Accordingly, one ro [r3] is 1/320th hkts. Line 1: one-third one To be read as 1/3 of one is = a third Line 2: two-thirds two To be read as 1/3 of two is = two-thirds Line 3: one-third one four To be read as 1/3 of four is = one and one-third Here, the scribe combined the result of one-third of one, and one-third of four, to find that five-thirds is equal to one-third of five. Line 4: //3 ro 1 ro /64 To be read as 1/3 of one/64 hkt is = [(//3* /320)+(/320)] = 5/960 = /192 = correct! One third of /64 is /192. Line 5: /3 ro 3 ro /32 To be read as 1/3 of one/32 hkt is = [(/3* /320)+(3*/320)] = 10/960 = /96 = correct! One third of /32 is /96. Line 6: //3 ro 1 ro /64 /16 To be read as 1/3 of one/16 hkt is = [(//3* /320)+(/320) + (/64)] = 6 2/3 ro = 20/960 = /48 = correct! One third of /16 is /48. Line 7: /3 ro 3 ro /32 /8 To be read as 1/3 of one/8 hkt is = [(/3* /320)+(3*/320) + (/32)] = 13 1/3 ro = 40/960 = /24 = correct! One third of /8 is /24. Line 8: //3 ro 1 ro /64 /16 /4 To be read as 1/3 of one/4 hkt is = [(//3* /320)+(/320 + /64 + /16)] = 26 2/3 ro = 80/960 = /12 = correct! One third of /4 is /12. Line 9: /3 ro 3 ro /32 /8 /2 To be read as 1/3 of one/2 hkt is = [(/3* /320)+(3*/320) + /32 + /8)] = 53 1/3 ro = 160/960 = /6 = correct! One third of /2 is /6. Line 10: //3 ro 1 ro /64 /16 /4 1 To be read as 1/3 of one hkt is = [(//3* /320)+(/320 + /64 + /16 + /4)] = 106 2/3 ro = 320/960 = /3 =correct! One third of 1 is /3. Line 11: /3 ro 3 ro /32 /8 /2 2 To be read as 1/3 of two hkts is = [(/3* /320)+(3*/320) + (/32 + /8 + /2)] = 213 1/3 ro = 640/960 = //3 = correct! One third of 3 is //3. Note that the scribed appears here to have tallied line numbers ten and eleven [see the check marks on the image] and found in each case that the result was accurate. Compare this to the similar tallying procedure on the table of elevenths. I am studying each and every transcribable entry for errors which may more clearly suggest the method(s) that generated these identities. Home Quest Guide
