Year '''105''' ('''[[Roman numerals|CV]]''') was a [[common year starting on Wednesday]] of the [[Julian calendar]]. At the time, it was known as the '''Year of the Consulship of Candidus and Iulius''' (or, less frequently, '''year 858 ''[[Ab urbe condita]]'''''). The denomination 105 for this year has been used since the early medieval period, when the [[Anno Domini]] [[calendar era]] became the prevalent method in Europe for naming years.

=== By topic ===

==== Art and Science ====
* [[Papermaking]] is refined by the Chinese eunuch [[Cai Lun]], who receives official praise from the emperor for his methods of making paper from tree bark, [[hemp]], remnant [[textile|rags]] and [[fish net]]s. Paper had been made in [[China]] from the [[2nd century BC]], but Cai Lun's paper provides a writing surface far superior to pure [[silk]] and is much less costly to produce. [[Bamboo and wooden slips]] will remain the usual materials for [[book]]s and [[scroll]]s in most of the world for another 200 years, and paper will remain a Chinese secret for 500 years.
