The astronomer [[Aristarchus of Samos]] was the first known person to propose a heliocentric model of the [[Solar System]], while the geographer [[Eratosthenes]] accurately calculated the circumference of the Earth. [[Hipparchus]] (c. 190&nbsp;– c. 120 BCE) produced the first systematic [[Timeline of astronomical maps, catalogs, and surveys|star catalog]]. The level of achievement in Hellenistic astronomy and [[engineering]] is impressively shown by the [[Antikythera mechanism]] (150–100 BCE), an [[analog computer]] for calculating the position of planets. Technological artifacts of similar complexity did not reappear until the 14th century, when mechanical [[astronomical clock]]s appeared in Europe.<ref name=insearchoflosttime>{{cite journal | last1=Marchant | first1=Jo | year=2006 | title=In search of lost time | journal=Nature | volume=444 | issue=7119| pages=534–538 | doi=10.1038/444534a | pmid=17136067 | bibcode=2006Natur.444..534M | doi-access=free }}</ref>
