Depósito de óleo 

This is "Depósito de óleo" by Candido Portinari, though the date of its making is unknown. The oil tanks rise like modernist monoliths. Their presence speaks to Brazil's industrial ambitions during a period of significant transformation. Portinari, whose work often grappled with the social realities of Brazil, here captures the tension between progress and the landscape. The tanks, bathed in a silvery light, contrast sharply with the darkened earth and the small, almost hidden, building below. This juxtaposition may suggest a critique of industrial development overshadowing the human element. Portinari, who was deeply committed to portraying the lives of ordinary Brazilians, conveys a sense of unease through the scale and isolation of the tanks. They seem to dominate not just the landscape, but perhaps also the lives of those connected to them. The painting then becomes a commentary on the economic shifts and their impact on Brazilian society, filtered through Portinari's empathetic lens.
