| Bronze Age |
Archaeologically, this era is defined by technology, but consider the tag to indicate roughly 3000-1000 BCE. Generally entries tagged with this will involve art. |
| Classical Era |
This tag is used to indicate the eras dominated by Greek and Roman civilization. In regions where those cultures had no influence, consider it to indicate roughly 1000 BCE to the early centuries of the Common Era. If a more specific date in the Common Era is known, that will be used. |
| Post-Roman/Early Medieval |
This tag is used when a more specific date isn’t available, covering very roughly the first millennium. |
| Medieval (general) |
This tag is used when a more specific date isn’t available covering very roughly the 11-14th centuries. |
| Renaissance (general) |
The Renaissance is defined differently in different countries, and generally a more specific date will be used. Consider this to cover roughly the 15-16th centuries. |
| Early Modern (general) |
This tag is used when a more specific date isn’t available, but consider it to cover roughly the 17-18th centuries. This tag is unlikely to be used much. |

The strict scope of this project cuts off at the 20th century, but this tag will occasionally be used when a source spills over. |
