Alcis

Tacitus mentions a divine pair of twins called the Alcis worshipped by the Naharvali, whom he compares to the Roman twin horsemen Castor and Pollux. These twins can be associated with the Indo-European myth of the divine twin horsemen (Dioscuri) attested in various Indo-European cultures. Among later Germanic peoples, twin founding figures such as Hengist and Horsa allude to the motif of the divine twins; Hengist and Horsa's names both mean "horse", strengthening the connection. In Scandinavia, images of divine twins are attested from 15th century BCE until the 8th century CE, after which they disappear, apparently as a result of religious change. Norse texts contain no identifiable divine twins, though scholars have looked for parallels among gods and heroes.
