The piece on the Malta temples needs revision. My findings are that obliquity changes to low at 3550bce. 3200bce was a tectonic event that changed the temples orientation; a tectonic rotation. Mnajdra south was built post event, around 2900 from one dating C14. Dodwell's obliquity increase came later as he found, at around 2345bce as said (there are corroborating indicators). Mnajdra built to low obliquity but later modified to a higher one, hence the 'wings' on the side, the only one like that.
