Raman signatures of the modern pigment (Zn, Cd)S 1- xSe x and glass matrix of a red bead from Magoro Hill, an archaeological site in Limpopo Province, South Africa, recalibrate the settlement chronology

Prinsloo, Linda Charlotta; Boeyens, Jan Christoffel Antonie; Van der Ryst, Maria M.; Webb, Geoffrey (Elsevier, 2012)

Two glass trade beads, one red and one yellow, retrieved from a secure archaeological context on Magoro Hill, an erstwhile Venda stronghold in South Africa’s Limpopo Province, were analyzed with Raman and photoluminescence ...
Towards refining the classification of glass trade beads imported into Southern Africa from the 8th to the 16th century AD

Koleini, Farahnaz; Prinsloo, Linda Charlotta; Biemond, Wim M.; Colomban, Philippe; Ngo, Anh-Tu; Boeyens, Jan Christoffel Antonie; Van der Ryst, Maria M. (Elsevier, 2016-05)

The universe in perspective

Boeyens, Jan Christoffel Antonie (University of Toronto Press, 2010-06)

Gödel’s rotating-universe solution of Einstein’s gravitational field equations is interpreted in real projective space. The compass of inertia is shown to coincide with the involuted geodesic of the closed manifold and ...
Unravelling the glass trade bead sequence from Magoro Hill, South Africa : separating pre-seventeenth-century Asian imports from later European counterparts

Koleini, Farahnaz; Prinsloo, Linda Charlotta; Biemond, Wim; Colomban, Philippe; Ngo, Anh‑Tu; Boeyens, Jan Christoffel Antonie; Van der Ryst, Maria M.; Van Brakel, Koos (BioMed Central, 2016-12-22)

Excavations conducted between 2010 and 2012 at Magoro Hill, a site in South Africa’s Limpopo Province frequented or intermittently occupied by African farming communities since the first millennium AD, yielded a substantial ...
