It does so by examining the frequency of signs in the proto-cuneiform tablets from the period c.3500-3000 BCE.  For those wishing to build up experiential understanding of life in the Neolithic and early Bronze Age near east, this article provides suitable references as well as practical explorations of the economic and productive activities of the people: rope-making from grass, basket-weaving from reads, baking, weaving of cloth from linen, breaking ground, sowing, reaping, making flour, etc.  <\/p>\n<p>The first part of the article look closely at the collection of artifacts in each period that are associated with the evolution of writing and mathematics in ancient Mesopotamia, examining noteworthy individual artifacts that showcase a key development.  <\/p>\n<p>The study uses the CDLI database of cuneiform documents, and software I&#8217;ve written that parse the files in the CDLI database, extracting counts, parsing signs, generating frequency distributions of signs, creating a proto-cuneiform glossary, and assisting in the quantitative analysis of artifacts and semi-automated translation (see CDLI parser software library written in Ruby).<\/p>\n<p><!--more--><\/p>\n<hr>\n<h3>The earliest written documents<\/h3>\n<p>Writing began c.3500 BCE in Uruk in southern Mesopotamia (Iraq) as the culmination of a series of innovations for better economic control.  These innovations simplified and extended a pre-existing quantitative tradition that appears to reach back as far as 8500 BCE (5 millenia prior).  <\/p>\n<p>What led to this pre-existing ancient quantitative tradition?  The impetus was the management (generation, collection, and redistribution, trade) of the surpluses produced following the transition to sedentary life.  Over time [<a href=\"#Charvat\/2002\">Charvat\/2002<\/a>], early Mesopotamian settled civilization increased agricultural yields through better tools and practices, leading to bigger harvests (barley, wheat, grain), the growth of livestock herds (sheep, goats, cows, pigs, birds) the extraction of animal products (milk, cheese, meat, eggs, wool, leather) and the rise of specialized craftsmen (brewers, carpenters, sculptors, potters, and weavers) manufacturing from grain, wood, stone, clay, flax (plant-based), wool and leather (animal-based).<\/p>\n<p>The innovations that led to writing and mathematics was initially concentrated in the city of Uruk with its early temple economy whose administrators needed to account for transactions (archaic book-keeping) as the contributing population grew expanding beyond what could be managed through trust relationships and collective memory.  The success of Uruk and its centrally managed economy led to growing power, influence, trade, and the spread of this new technique.  An early rival, Susa in Elam, shows a similar arc in written and mathematical artifacts around the same period, followed by the spread of this new mathematical and literate technology wider afield through the various city-states of southern Mesopotamia and western Khuzistan.<\/p>\n<h3>Cultural Exploration: Ways of Life and Thought<\/h3>\n<p><strong>Daily Life<\/strong><br \/>\n[Chavrat\/2002] describes ways of life during the Neolithic through to the Early Bronze Age (c.3500) when writing began.<\/p>\n<p><strong>The Sumerian Precedence Debates (Disputation Literature)<\/strong> provide first-hand insight (stylized) into the ways of life of the Sumerians.

In pre-Uruk V times this could be explained if the document recorded a physical transaction\/collection of separate tokens gathered, rather than the scribe reformulating the number using the canonical representation (i.e. bundling into the next higher metrological unit).\n<li><strong>What might have motivated the specific metrological systems?<\/strong>\n<ol>\n<li>No step between units was larger than ten, allowing all calculations to be able to be made with counters (tokens) and fingers.\n<li>By constructing the factors judiciously to match conventional quantity bundles, one encoded common mathematical operations to allow correct reasoning without having to do the math.\n<ul>\n<li>Example from <a href=\"http:\/\/projectbritain.com\/moneyold.htm\" rel=\"noopener noreferrer\" target=\"_blank\">pre-decimal Britain<\/a>.  12 pence to a shilling makes it easy to price dozens, e.g. if an egg is 4 pence, then a dozen eggs is 4 shillings.\n<li>Made-up example to motivate SZE system: a bowl of grain (N39, SILA3) is wage for one day&#8217;s labor.  a typical gang of workman has 5 laborers (ERIM).  5 N39 sila to an N01, so 1x N01 is a day&#8217;s wages for a gang of laborers.  6 days working for a week.  6 N01 to an N14, so 1x N14 is a week&#8217;s wages for a gang of laborers.  Now it is easy to calculate grain requirements for wages.  3 weeks work by a single work-gangs is will cost 3x N14.  3 weeks work by two work-gangs is 6x N14.\n<\/ul>\n<\/ol>\n<\/ul>\n<p><strong>Pre-Uruk V (before 3500 BCE)<\/strong><br \/>\nCDLI (searched 11th Jan 2020) had 217 <a href=\"https:\/\/cdli.ucla.edu\/search\/search_results.php?SearchMode=Text&#038;requestFrom=Search&#038;Period=Pre-Uruk&#038;requestFrom=Submit+Query\" rel=\"noopener noreferrer\" target=\"_blank\">Pre-Uruk V artifacts<\/a>, 77% (167) <a href=\"https:\/\/cdli.ucla.edu\/search\/search_results.php?SearchMode=Text&#038;requestFrom=Search&#038;Period=Pre-Uruk&#038;ObjectType=Bulla&#038;requestFrom=Submit+Query\" rel=\"noopener noreferrer\" target=\"_blank\">bullae (clay envelopes)<\/a>, 19% (41) <a href=\"https:\/\/cdli.ucla.edu\/search\/search_results.php?SearchMode=Text&#038;requestFrom=Search&#038;Period=Pre-Uruk&#038;ObjectType=other&#038;ObjectRemarks=token&#038;requestFrom=Submit+Query\" rel=\"noopener noreferrer\" target=\"_blank\">loose tokens<\/a>, 4% other (6 Seals<br \/>\n1 Tablet, 1 Disk, 1 Tag).<\/p>\n<p>The bullae have enclosed tokens.

Or it could be the purchase of rope for grain (grain payments were standard).  Regardless the 10 SILA (standard 0.8L bowls) of barley would be 2 days of standard wages in grain-payment per rope.  It may indeed be the two days to fashion a finished vessel including the straps from finished ropes.  If this interpretation is true, it suggests that the temples controlled the central payment and consolidation of many intermediate products required to manufacture useful finished articles, coordinating grain payments between artisans of different types.  This is an early precursor to the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Bala_taxation\" rel=\"noopener noreferrer\" target=\"_blank\">bala taxation system<\/a> in place during Ur III empire (c. 2000 BCE).  BALA first appears in Uruk IV signs (1 instance, <a href=\"https:\/\/cdli.ucla.edu\/search\/archival_view.php?ObjectID=P001399\" rel=\"noopener noreferrer\" target=\"_blank\">tablet P001399<\/a>, records exactly such a transaction) then increases in Uruk III sign frequency (24 instances).  This would later give way to a silver-based economy in the Ur III empire times (1 shekel of silver = 300 sila (L) of barley grain).

The keeping of flocks led to nomadic movement of animals and people following grazing pastures, and moving between the alluvial plain the summers and the mountains in the winters [<a href=\"#Charvat\/2002\" rel=\"noopener noreferrer\" target=\"_blank\">Charvat\/2002<\/a>]  Wild sheep had hair not wool.  After domestication, sheep were selectively bred for wool.  Sheep provided milk, cheese, wool, and when slaughtered, meat, oils and fats, and skins.<\/p>\n<p><strong>How were <a href=\"https:\/\/en.wikipedia.org\/wiki\/Sheep_shearing\" rel=\"noopener noreferrer\" target=\"_blank\">sheep sheared<\/a> for SIG2 (wool)?<\/strong> For some breeds, when the wool is &#8220;ripe&#8221; (ready) it will naturally start to shed (roo) its wool.  Hand rooing (plucking) can accelerate this.  By medieval England at the height of the wool trade (c.1400 CE, or 6,000 years after tablet P200044), the entire <a href=\"https:\/\/www.deverehouse.co.uk\/?page_id=162\" rel=\"noopener noreferrer\" target=\"_blank\">sheep-to-wool value chain<\/a> was well developed with custom inventions for every step of the process path.<\/p>\n<p><strong>Why the cross-in-circle sign for UDU (sheep)?<\/strong><br \/>\nMost animal signs in proto-cuneiform resemble the animal, except <a href=\"https:\/\/en.wikipedia.org\/wiki\/Sheep\" rel=\"noopener noreferrer\" target=\"_blank\">sheep<\/a> and <a href=\"https:\/\/en.wikipedia.org\/wiki\/Goat\" rel=\"noopener noreferrer\" target=\"_blank\">goat<\/a>.  Why are sheep (UDU) a cross within a circle, and goat (MASZ) a cross (no circle)?  Imagine looking at a sheep head on.  Plump wooly head (circle), with the vertical axis defined by broad nose ridge and horizontal axis defined by the extended ears.  With goats, no wool but same distinctive cross axes for the face (cross-without circle).

There are no other examples of this level of written complexity in Uruk V, and because in addition this tablet belongs to a collection of unprovenanced finds that have not yet been published, my working assumption is that this may be an incorrect assignment.  Nevertheless, what is recorded is fascinating: <\/p>\n<blockquote><p>&#8220;50 goat (MASZ), 2 cow (AB2) for roasting? (NE)&#8221; and on the reverse: &#8220;1 cover (SZU2), 14 at\/for Eridu (NUN)&#8221;.<\/p><\/blockquote>\n<p>  There is no archaeological context as to what it was recording or why, but the fact that such records were being kept, using the new technology of writing, with the additional invention of ideographic signs describing the transaction, is remarkable, as it shows the evolution of the writing\/sign invention process from pure numeric only having quantity information (presumably commodity was obvious to the record-keeper and user, from context) to simple numero-ideographic that also add commodity information, and finally to complex records with quantity, commodity, and intention recorded.  <\/p>\n<p>A plausible scenario is provision for a feast.  How many people might be fed from this provision list?  A male cow of average 1000 lbs weight will have <a href=\"https:\/\/www.quora.com\/How-many-people-can-one-cow-feed-on-average\" rel=\"noopener noreferrer\" target=\"_blank\">~40% consumable meat<\/a> (~400lbs) due to live weight contribution from blood, hide, head, hooves, lungs, viscera, bone, fat. (<a href=\"https:\/\/www.answers.com\/Q\/How_many_people_can_an_entire_cow_feed\" rel=\"noopener noreferrer\" target=\"_blank\">high est<\/a>., low est.), which would feed approx 800-1600 people depending assuming 1\/4 lb (110g) &#8211; 1\/2 lb (220g) portion size.  An average goat of 100lbs weight may have ~40lbs of consumable meat and feed 80-160 people  (1 cow = 10x goats) assuming <a href=\"https:\/\/en.wikipedia.org\/wiki\/Goat_meat#Production\" rel=\"noopener noreferrer\" target=\"_blank\">similar meat to carcass ratio for goats<\/a>.  This suggests this provision list would have been enough to feed 5,600-11,200 people.  Given the sign for Eridu, which had the earliest temples and was viewed as the holy city of Sumeria, this may have been provision for a large festival.  Estimates are that <a href=\"https:\/\/en.wikipedia.org\/wiki\/Eridu#History\" rel=\"noopener noreferrer\" target=\"_blank\">ancient Eridu had at least 4,000 inhabitants<\/a> during the period before this (Ubaid, 4500-3800 BCE), which may have increased and been supplemented by festival visitors from nearby settlements (Ur was 12km away).<\/p>\n<div id=\"attachment_4466\" style=\"width: 418px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" aria-describedby=\"caption-attachment-4466\" loading=\"lazy\" src=\"https:\/\/mathscitech.org\/articles\/wp-content\/uploads\/2020\/02\/screenshot.7448.png\" alt=\"\" width=\"408\" height=\"482\" class=\"size-full wp-image-4466\" srcset=\"https:\/\/mathscitech.org\/articles\/wp-content\/uploads\/2020\/02\/screenshot.7448.png 408w, https:\/\/mathscitech.org\/articles\/wp-content\/uploads\/2020\/02\/screenshot.7448-254x300.png 254w, https:\/\/mathscitech.org\/articles\/wp-content\/uploads\/2020\/02\/screenshot.7448-127x150.png 127w, https:\/\/mathscitech.org\/articles\/wp-content\/uploads\/2020\/02\/screenshot.7448-400x473.png 400w\" sizes=\"auto, (max-width: 408px) 100vw, 408px\" \/><p id=\"caption-attachment-4466\" class=\"wp-caption-text\"><a href=\"https:\/\/cdli.ucla.edu\/search\/archival_view.php?ObjectID=P342526\" rel=\"noopener noreferrer\" target=\"_blank\">Tablet MW 0188\/034<\/a>, with proposed translation: &#8220;50 goat (MASZ), 2 cow (AB2) for roasting?

The ideographic signs (proto-cuneiform), produced with the sharp end of a stylus for drawing the various curves involved, began to be simplified, and mimicked using the wedge end of the stylus and straight line-segment impressions.<\/p>\n<p>[figure &#8211; evolution of signs, Nissen, Englund, and CDLI sign list]<\/p>\n<hr\/>\n<h2>Appendices<\/h2>\n<h3>Appendix 1: Learning the Ancient Skills<\/h3>\n<p>If you live in a British city of reasonable size, you are likely to find, nearby, opportunities to learn the skills recorded by the ancient peoples, and taste what parts of their lives might have been like.
