Timay al-Imdid (Arabic: تمي الإمديد , Coptic: ⲑⲙⲟⲩⲓ ⲡϭⲓⲙⲉⲛⲧⲏϯ pčhimentēti), the ancient Thmuis[3] and Mendes, is a city and markaz in Dakahlia Governorate of Egypt. The estimated population of the markaz in 2019 was 201,956, with 19,366 living in urban areas and 182,590 in rural areas.[2]
The name Timayy is derived from the Coptic word ⲑⲙⲟⲩ tmoui, meaning "island", a fairly common Coptic place name element. In this case it is an abbreviation of Demotic tꜣ-mꜣw.t-n-pr-bꜣ-nb-ḏd.t "the island of Mendes". The second part Amdid (older form Mandid or Mandadi) comes from, a compound toponym the first part of which is ϭⲓⲏ "border, edge" and the second one comes from Egyptian pr-bꜣ-nb-ḏd.t "temple of Aries of the lord of ḏdt" which is also the source of .[4]
There were Coptic revolts in Timayy in 725-726 and 831-832. It had a Christian bishopric.[3]
The 1885 Census of Egypt recorded Timay al-Imdid (as "Tami-el-Amdid") as a nahiyah under the district of El Senbellawein in Dakahlia Governorate; at that time, the population of the town was 1,338 (694 men and 644 women).[5]
