"In Nadur the purposes of costume is disguise, in other words, simply not to be recognised. Consequently grotesquely disguised crowds overrun the streets; the costumes consisting mainly of haphazard, coarse guises made of sack, sheets, wigs and incongruous make-up. The local participants are often silent for most of the time in order to make sure that they remain unidentified - so much so that is sometimes referred to as the Silent Carnival. The floats lose much of the grandeur, which the Valletta carnival accords them, and are often no more than carts released from their ubiquitous role on the farms and brought to the streets of Nadur.
Within this absurd set-up it is not uncommon to catch sight of placards with ambiguous, snide remarks daubed in paint directed at both private and public personalities, which in order to avoid being regarded as libellous are often veiled reference, very difficult to gauge for first-time visitors."
the dates for carnival in Gozo are given here as 17th to 28th Feb
