大篆是西周时期普遍采用的字体，相传为夏朝伯益所创。针对不同的书写媒介，大篆亦有金文（或称“钟鼎文”）、籀文之别。
金文是铭刻在古代一切铜器上的文字，西周和春秋时期，各诸侯国的字体有些区别，出土的各种铜器上铭刻的文字并不通用，年代不同也有所变化。
籀文是周朝晚期使用的文字，为显示国威，于是将原本的钟鼎文的文字，繁化而成为籀文，详见《史籀篇》。亦是小篆的前身，由于在周朝晚期史籀作的《史籀篇》中收藏有223个字，因此叫籀文，据说“籀”的意思是“诵读”。唐朝时出土的“石鼓文”据考证是周宣王打猎时所刻，推测和《史籀篇》中文字相似，是目前可见，最接近籀文的代表。

Large Seal script or Great Seal script (Chinese 大篆 Dàzhuàn) is a traditional reference to Chinese writing from before the Qin dynasty, and is now popularly understood to refer narrowly to the writing of the Western and early Eastern Zhou dynasties, and more broadly to also include the oracle bone script. The term is in contrast to the name of the official script of the Qin dynasty, which is often called Small or Lesser Seal Script (小篆 Xiǎozhuàn, also termed simply seal script). However, due to the lack of precision in the term, scholars often avoid it and instead refer more specifically to the provenance of particular examples of writing.
