Ca. 100-300 AD.A beautiful green, free-blown glass bottle featuring a squat body on a concave base, a short cylindrical neck, and an everted rim. Some weathering and incrustation occur throughout the bottle; the outside shows a beautiful iridescence. While glass-making had been practiced for centuries, the Romans invented the glassblowing technique in the 1st century BC, which revolutionized this craft. Roman glassmakers reached incredible artistic heights with both free-blown vessels and mould-blown forms and decorations. By the Late Roman period (4th-5th century AD), good quality glass tableware such as this one was relatively uncommon and could have been used as a showpiece and perhaps even as an indicator of social standing or wealth within the Late Roman household, especially when displayed in the public area of the house.
