The figures in the original publication are adaptations of rock art motifs, and the sources of the original photographs were cited in the description of each figure [
1]. We have since understood that additional permission is required for the adaptation of a photograph. The required permissions have now been obtained. However, we have replaced Figures 3, 5–8 and 10 with either a different adaptation, or with the original photograph, at the request of the copyright holder. We have changed the image description of Figure 11 in order to reflect the granted permissions, as requested by the copyright holder. Figure 8 has been replaced with a depiction of an armed conflict on a boat from Scandinavian rock art, specifically from Tanum in Sweden. Scandinavian Bronze Age rock art is known to contain depictions of technology, such as weapons and boats, as well as scenes that refer to warriors and armed conflict [
2]. The corrected figures appear below, including a new description. The revision of the image descriptions led to corresponding changes in the references cited in the text.
Lastly, there was an error in reference [49] in the original publication. The correct citation is: Taçon, P.S.C.; Wilson, M.; Chippindale, C. Birth of the Rainbow Serpent in Arnhem Land rock art and oral history. Archaeol. Ocean. 1996, 31, 103–124.
The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
