Donatist ( Donatus ) bishop in Numidia, maltreated with a delegation of bishops in Vegesela (Numidia) by Macarius. M. was taken prisoner and - probably on 29 Nov. 347 AD - executed, according to the Donatist Acts  by being pushed off a high cliff. He was buried as a martyr in Nova Petra and revered by the Donatists. There is archaeological evidence for a memoria domni Marchuli in Vegesela (Ksar el Kelb in Algeria).
