Horologium
Horologium est instrumentum quo tempus definitur, indicatur, ordinatur. In usu generali hodie, horologium est quaelibet res quae spatia temporis metitur et monstrat. Horologia armillaria (vel horologia gestabilia) et alii temporis mensores qui portari possunt ab horologiis saepe distinguuntur.

Horologium est unum ex primorum inventorum humanorum, ad tractandas necessitates spatiorum temporis constanter metiendorum quae unitatibus naturalibus sunt brevioria, praecipue inter quas dies, menses lunares, annos. Machinae quae nonnullis physicae rationibus utuntur per millennia adhibitae sunt, in horologiis hodiernis finientes.

Studium temporis mensurati horologia appellatur.

Solaria et aliae res 
Solarium, quod tempus diei umbram solis in lapidem cylindricum deiectam metitur, latissime antiquitate adhibitum est.

Horologia candelae et virgulae turis quae celeritatibus notis deflagrantur etiam ad aestimandum temporis transitum adhibita sunt.

In clepsydra vitri, arena tenuis per foramen perparvum constanter funditur et sic transitum certi temporis spatii indicat.
