Nice ! that's Samian ware, from the Roman European provinces (1st - 3rd c.) Oil lamp from Africa (Thysdrus - el-Jem) 5th-6th c. AD (handle restored)
I love ancient artifacts as much as I love ancient coins. Speaking of such things as the two posted above, below is a fitting artifact from my collection: Terra Sigillata (Roman “Redware”) plate fragment. Tau-Rho / Staurogram within concentric circles. ca. 4th-6th Century AD, North Africa. (177 mm. at widest point.)
