 The works of Christián Carman deserve a special mention since they make him a top-ranked international specialist in ancient astronomy due to their quantity and quality. His first works focused on Ptolemy’s calculations and explanations (Carrman 2009, 2010a, 2011, 2015; Recio and Carman 2018), but soon his interest expanded to other authors, such as Aristarchus (2014), Martianus Capella (2017a), Copernicus (2018), and Heraclides of Pontus (2017b). In an additional line of research, Carman collaborated with the renowned scholar James Evans in a detailed study of the Antikythera mechanism which resulted in several very relevant works (Evans, Carman, and Thorndike 2010; Carman, Thorndike, and Evans 2012; Carman and Evans 2014). Carman developed further his analyses of the mechanism, in some cases in single-authored works and in other cases in collaborartion with other international scholars (Anastasiou, Seiradakis, Carman, and Efstathiou 2014; Carman and di Cocco 2016; Carman 2017c). Finally, Carman has recently extended his collaboration with Evans beyond the original interest in the Antikythera mechanism, examining other issues in ancient astronomy (Carman and Evans 2015).
